Can't access HTTPS sites-message says can't establish a secure connection

Whenever I try to access any secure (HTTPS) site, I get a message saying that Safari can't establish a secure connection. I'm running on an I Book G4, 10.3.9. This started a couple of weeks ago. It had been fine.
I have an IMac runnning the same operating system and the same Safari version and that works fine.
Any ideas? Thanks
I Book G4 Mac OS X (10.3.9)

You need to update OS X to v10.8.5
Click your Apple  top left in your screen. From the drop down menu click Software Update.
OR, open the App Store then select Updates from the menu top of the App Store window.
Then follow the instructions.
When the updates are finished, try Safari.
Very very important to keep your Mac's software up to date.

Safari Mac can't access web site that Windows can

None of my Macs can access the site http://cards.123greetings.com . I get Can't Find Server messages in both Safari and Firefox. (Clearing caches doesn't help)
cards.123greetings.com is part of a large free card site that did a major upgrade in October. It still renders correctly on a PC running Windows XP Home which runs on the same network as the Macs, so it's not an isp problem.
Since both Macs (G4 iBook running 10.3, MacBook running 10.4) have the same Can't Find Server problem with both Safari and Firefox, it appears that some setting in the Macs themselves is causing this.
Any help or insight would really be appreciated - Thanks!

A big Thank You to Mulder for letting me know that you can access the site (with Mac Safari I presume) - That's good news.
The bad news: I still can't access the site.
The problem affects two separate computers and four browers. Taking your advice, I repaired permissions and logged in as a new account on both machines. Unfortunately that didn't work.
I next tried accessing the site on the MacBook through Parallels running Windows XP Home. The site came up fine using Internet Explorer.
Then I realized that Parallels operates with a different ip address. So I went back on the Mac using a proxy, and the site came right up.
It now seems that the ip addresses of both computers are being blocked at some level. I want to thank Mulder for replying and virtually ruling out that it might be a Safari issue. I'm now "off topic" and will no longer post in this section. But I'm also over my head... If anyone has advice about how to proceed now, I'd truly appreciate it.
Thanks!

I can no longer access facebook from my macair and when i try the following error message appears "unable to establish a secure connection to the server.

I have had no issue accessing Facebook in the past using my MacAir. Last night each time I would try and access the page, an error message would appear, saying that unable to establish a secure connection to the server "www.facebook.com"". The problem continues this morning. I have not updated any software or made any changes. One minute it was working, the next it was not. I do not have any parental controls; I have deleted the cookies; and I have reset safari. I can access all other websites that I have tried. I am using Version 6.0.4.

From your Safari menu bar click Safari > Preferences then select the Privacy tab.
Click: Remove All Website Data
Then delete the cache.
Now open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
If nothing above helped, troubleshoot Safari extensions.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
If it's not an extensions issue, restart your internet modem and router. Then quit and relaunch Safari and try Facebook.

[SOLVED] Lynx Browser: Can't access https sites.

Hello, an arch newbie here. I hope I posted in the right section.
I'm having a little bit of trouble using the text-based browser "lynx". I made sure to precompile lynx with ssl options before make and installing. Yet, when I try to access a https site, it throws the message:
"Alert!: This client does not contain support for HTTPS URLs.
lynx: Can't access startfile https://www.archlinux.org/"

Not sure what I'm missing. My first guess is to uninstall it, and remake it with different .configure options. I'm hesitant though, because it seems like it is already set up to handle https sites correctly. I've been trying to make this work for a couple days.
Thanks in advance for your time, I appreciate any advice.

This is a bad idea. Now you have untracked files in your root directory and there is a fair chance this could lead to a file conflict when running pacman in the future. You should make a PKGBUILD for anything you want to build yourself.

Ipad2 tried to update numbers and keynote apps, now can't access either and message says unable to download ?

Tried to update app's numbers and keynote, now can't access either of them and message says app can't be uploaded at present, so now both apps just show blank download bar, and I can't open them up at all. Can anyone help ?

Remember that you can always try finishing the downloads in iTunes on your computer and then sync the iPad to try to move the apps to the iPad.
You can try any of these suggestions as well.
Make sure that you do not have a stalled download in iTunes - a song or podcast .... if you have a download in there that did not finish, complete that one first. Only one thing can download at a time on the iPad so that could be what is causing the problem.
If that doesn't work - sign out of your account, restart the iPad and then sign in again.
Settings>Store>Apple ID. Tap your ID and sign out. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Go back to Settings>Store>Sign in and then try to update again. Tap one waiting icon only if necessary to start the download stream.
You can also try deleting the waiting icons - tap and hold down on an icon until it wiggles - the tap the X on the icon to delete it. Then try to download again.
You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your app preferences and device settings again.

Wha wha wha?? Can only access https sites, not http?

This is odd. I don't have a firewall. I can get on https but not http. Software Update also doesn't work, nor does anything iTunes does that needs the internet.
Also, I suddenly need to type in an administrator password any time I modify or move anything in the Applications folder. I didn't used to have to do that.
I don't know if this is related, but around the time this happened, I was trying to fix some annoying Time Capsule issue. I was able to finally fix it by using the Terminal and typing in some unix stuff:
sudo chflags nouchg /Volumes/Data ("Data" being the name of the data folder in Time Capsule)
sudo chmod 775 /Volumes/Data
I used the same commands on my wife's MacBook, which was having the same Time Capsule issue, and she can still connect to the internet just fine. Anyone have any idea what's going on?

I'm having a problem accessing Bupers Online using my CAC reader. I get an error that says safari can't establish a secure connection to the website. Does anyone know how to fix this?

I am having a problem accessing Bupers Online on OS X Mountain Lion. I get an error that says Safari cant establish a secure connection with Bupers Online. Does anyone have any tips to access Bupers?

I don't use CAC certificates, but since updating to 10.9.3, I too am getting the same error, BUT only with some HTTPS sites (e.g., https://webmail.pairlite.com), not all. Meanwhile, Firefox (was 12.0, now 29.0.1) connects with no issue.
I too have verified date/time is set automatically, checked for (and fixed) disk integrity errors and permissions, and rebooted, all to no avail.
Update:
Well...heck. Tried accessing the problematic site via the Guest account, and that WORKED. So...back to the drawing board.

Can't open the page ---- because can't establish a secure connection

I recently upgraded to 10.4.8 and had no apparent problems.
There may, however, have been one resulting problem in that when I try to open one of my bookmarked locations, I get a message
"Safari can’t open the page --- because it couldn’t establish a secure connection to the server"
I tried emptying the cache and that didn't help.
Any thoughts ?

thanks

Ok - I figured it out myself as soon as I posted this question. I went to my IPad settings - not the Settings in the Pages app. Problem fixed.

Can't access some sites when using Aiport Express, why?

I'm using Windows 7 and my router is a wireless Apple Airport Express that is approximately two years old. Suddenly I can't access some sites (for example www.sthlm.friskissvettis.se, or www.vegetarian-shoes.co.uk, some streamed tv-shows on svtplay.se, and a number of other random sites) when connecting to internet with my router. It worked good until recently and I'm fairly sure this problem emerged when my ISP upgraded from 10/10mbit to 100/10mbit speed. Most other sites like facebook and google works fine.
When using my network cable to connect to internet everything works fine and I can access these sites.
Firmware is current and I've tried reseting the router to factory defaults.
Tried different browsers, and I can't ping the "blocked" sites either. Tracert www.sthlm.friskissvettis.se starts with 10.0.0.1 and continues through a number of long addresses until it says timeout. The last working address before timeout was sth-tcy-ipcore01-ge-0-2-0.neq.dgcsystems.net [83.241.252.13], if it matters. Tracert www.vegetarian-shoes.co.uk also eventually gives me a timeout.
When the network cable is plugged in, I still get timeout on tracert www.sthlm.friskissvettis.se even though I can access the site in Chrome. Weird. www.vegetarian-shoes.co.uk doesn't give me a tracert timeout when the cable is plugged in, and I can access the site as usual.
I've tried changing DNS servers to use opendns servers instead, but to no use.
I've tried pinging these two sites with a lower MTU packet size (with this method: http://www.richard-slater.co.uk/archives/2009/10/23/change-your-mtu-under-vista- or-windows-7/), but still can't access them through ping...
I don't know what to do anymore.... any suggestions???
Thanks

Hi Punice
first try to disable JavaScript from : Firefox button (or Tools menu) > Options > Content panel > '''UNcheck''' Enable JavaScript.
if the above does not help check with a few malware/virus scan programs for virus. You need to use all programs because each detects different malware. Make sure to update each program to get the latest version before doing a scan.

Can't open HTTPS sites on Mac

Hello there, I'm using a MacBook Pro mid 2012 and my Safari stopped to load HTTPS pages and it says that it can't establish a secure connection. After about two hours looking for some answers, I think I found something, I need two certificates and both have "x509" in their names. Can someone help me to solve this HTTPS problem? I think the certificates are the right way to solve it, but I'm not sure.
I'm running the last update of MacOSX Yosemite.

This could be a complicated problem to solve, as there are several possible causes for it.
Back up all data, then take each of the following steps that you haven't already taken. Stop when the problem is resolved.
Step 1
From the menu bar, select
           ▹ System Preferences... ▹ Date & Time
Select the Time Zone tab in the preference pane that opens and check that the time zone matches your location. Then select the Date & Time tab. Check that the data and time shown (including the year) are correct, and correct them if not.
Check the box marked
          Set date and time automatically
if it's not already checked, and select one of the Apple time servers from the menu next to it.
Step 2
Start up in safe mode and log in to the account with the problem.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
If the problem is not reproducible in safe mode, then it's caused by third-party "anti-virus" or "security" software. If you know what that software is, remove it as directed by the developer after backing up all data. If you don't know what it is, ask for instructions.
Step 3
Triple-click anywhere in the line below on this page to select it:
/System/Library/Keychains/SystemCACertificates.keychain
Right-click or control-click the highlighted line and select
          Services ▹ Show Info
from the contextual menu.* An Info dialog should open. The dialog should show "You can only read" in the Sharing & Permissions section.
Repeat with this line:
/System/Library/Keychains/SystemRootCertificates.keychain
If instead of the Info dialog, you get a message that either file can't be found, reinstall OS X.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. Open a TextEdit window and paste into it by pressing command-V. Select the line you just pasted and continue as above.
Step 4
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
In the upper left corner of the window, you should see a list headed Keychains. If not, click the button in the lower left corner that looks like a triangle inside a square.
In the Keychains list, there should be items named System and System Roots. If not, select
          File ▹ Add Keychain
from the menu bar and add the following items:
/Library/Keychains/System.keychain
/System/Library/Keychains/SystemRootCertificates.keychain
Open the View menu in the menu bar. If one of the items in the menu is
          Show Expired Certificates
select it. Otherwise it will show
          Hide Expired Certificates
which is what you want.
From the Category list in the lower left corner of the window, select Certificates. Look carefully at the list of certificates in the right side of the window. If any of them has a blue-and-white plus sign or a red "X" in the icon, double-click it. An inspection window will open. Click the disclosure triangle labeled Trust to disclose the trust settings for the certificate. From the menu labeled
          Secure Sockets Layer (SSL)
select
          no value specified
Close the inspection window. You'll be prompted for your administrator password to update the settings.
Now open the same inspection window again, and select
          When using this certificate: Use System Defaults
Save the change in the same way as before.
Revert all the certificates with non-default trust settings. Never again change any of those settings.
Step 5
Select My Certificates from the Category list. From the list of certificates shown, delete any that are marked with a red X as expired or invalid.
Export all remaining certificates, delete them from the keychain, and reimport. For instructions, select
          Help ▹ Keychain Access Help
from the menu bar and search for the term "export" in the help window. Export each certificate as an individual file; don't combine them into one big file.
Step 6
From the menu bar, select
          Keychain Access ▹ Preferences... ▹ Certificates
There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to CRL.
Step 7
Triple-click anywhere in the line of text below on this page to select it:
/var/db/crls
Copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
A folder named "crls" should open. Move all the files in that folder to the Trash. You’ll be prompted for your administrator login password.
Restart the computer, empty the Trash, and test.
Step 8
Triple-click anywhere in the line below on this page to select it:
open -e /etc/hosts
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in the same way you launched Keychain Access.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. A TextEdit window should open. At the top of the window, you should see this:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1                              localhost
255.255.255.255          broadcasthost
::1                                        localhost
If that's not what you see, post the contents of the window.

Can't find view menu, can't access any sent messages. Really stinks.

It really stinks can't access my sent messages. Please, put View Menu back where it was. View Menu made easy for user like me who have little computer knowledge. What you did really sucks bigtime.

This is how Thunderbird works.
When you get it it has no menu bar.
<img alt="" src="https://support.cdn.mozilla.net/media/uploads/images/2014-08-09-17-05-10-29035c.png">
Pressing Alt or F10 make he following happen
<img alt="" src="https://support.cdn.mozilla.net/media/uploads/images/2014-08-09-17-05-18-8c6d27.png">
These key strokes and their results are not Thunderbird either. They are standard in your operating system. And most certainly in the case of the Windows 7 64bit both you and I are using.
Airmail tells you to select a menu
<img alt="" src="https://support.cdn.mozilla.net/media/uploads/images/2014-08-09-17-05-27-ee88ac.png">
When you hover over it another fly out menu appears
<img alt="" src="https://support.cdn.mozilla.net/media/uploads/images/2014-08-09-17-05-35-f7edbb.png">
Yet you say this does not happen which indicates more wrong than just a missing menu.
However there is vet another way to get a menu bar. You right click the toolbar between the Quickfilter Icon and the Menu Icon and select the menu bar from that menu.
<img alt="" src="https://support.cdn.mozilla.net/media/uploads/images/2014-08-09-17-15-41-49cd6f.png">
Now that there are pictures, do any of these methods work, or do we need to look deeper into your installation.

Can't update due to message saying a prior update is still running and to reboot, but I have rebooted 4 or 5 times

Can't update due to message saying a prior update is still running and to reboot, but I have rebooted at least 4 or 5 times What do I need to remove to get the install to work?
I am stuck at FireFox 3.6.18 as no update actually installs, even when I am logged in as the admin.
i am running XP SP3
I have the update files for version 4, 6, 8, and 10. IF I can figure out the error - probably in the registry - which update should I start with

If there are problems with updating then best is to download the full version and uninstall the currently installed version and delete the Firefox program folder to remove any leftover files.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 10.0.x: http://www.mozilla.org/en-US/firefox/all.html
*Firefox 3.6.x: http://www.mozilla.org/en-US/firefox/all-older.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data because all profile folders will be removed.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Delete the iWeb preference file, com.apple.iWeb.plist, that resides in your Home/Library/Preferences folder. Then launch iWeb and see if it opens.
What happened was trying to open the html file reset the file path that iWeb saves in its preference file to tell it where to go when you launch iWeb. Deleting the pref file and launching iWeb creates a new file and iWeb looks in your Users/Home/Library/Application Support/iWeb folder for the Domain.sites2 file it uses to create your site.
