Safari can't browse to secure site

We have an application that we are trying to access with Safari on the iPad and the iPhone. When browsing to the page, we get an error message. The site we are trying to get to is www.mainport.org
Cannot Open Page
Safari cannot open the page because it could not establish a secure connection to the server.
Thanks in advance for your help and ideas

tested:
iPhone with 3.x -> error
iPad with 3.x -> error
iPhone with IOS4 -> works
==> IOS4 on iPad should fix the issue

Can't access some secure sites through proxy?

can't access some secure sites through proxy server on osx it just keeps going local authority couldn't be contacted, i had the same problem with parental controls, but now that is off and its still doing it, is there a setting or something i need to enable?

In my original post, not today's, I had said I was having the issues on the Mini, running OSX 10.6.8 and Safari v.5.1.5 for my bank's pill pay. I should have been more specific as to which machine and OSX Safari browser I'm having the T-Mobile problem with. My mistake.
It is on both the MacMini and now the Air too. A moment ago, I was able to log in to my.t-mobile.com on the Air, but after putting into my Bookmarks folder, I can't do it anymore. The Log in button comes up greyed out instead of green.
I'm also still having trouble with my bank's bill pay section on both computers too.
I wonder if it's related to the saving of the log in info or putting in the Bookmark Folder?

Safari can't establish a secure connection to the server

Hello,
I am wondering if someone can kindly help me solve the following problem? I have been trying to troubleshoot myself, but it seems that the problem persists.
Issue
I am having problems asscessing a wireless web login. The University that I attend allows students to access the wireless web by entering their login and password. When a new browser session is started, it automatically directs to the wiresless web log in. Initially, I had no problems and could easily access log into the site. Recently, I have had a issue where I try to log in and I get one of two error messages:
Safari can't open page "xxxxxx" because Safari can't estabish a secure connection to the server "xxxx"
Your login was processed successfully but a DNS Timeout occured. You will need to close and restart your browser in order to reach your orginal desitnation.
Notes:
Issue #1 happens the most often.
When issue #2 happens, I close my browser and open a new one but the page remains blank.
The wi-fi shows full strength and all others in the room have the ability to log on/off with no problems.
I have no problems with other secure sites when accessing from home wireless connection.
Troubleshooting
I have tried several things:
Date and Time - correct
Parental Controls - none are set
Keychain First Aid - no errors
Another User Account - I have tried using a different user account and the problem continues
Used another browser - I have tried using Firefix, same problem
Open DNS - I have added DNS servers 208.67.222.222 and 208.67.220.220 but the problem continues
Safari Clean Up - I have emptied cache, cleared history, reset safari, same problem
I have tried to research the issue and troubleshoot as best as I can but nothing seems to work. I am somewhat new to Mac's but am pretty savy but need a bit of guidence to figure this one out as I am not sure exactly what I need to do and don't want to mess up any settings any further and compound the issue. It is quite frustrating as I am unable to access the internet and class website during class.
I should mention that at one point I had a scan/clean app installed. Before this app was installed it seems to work, however, I can't directly link the timing. I can't remember exactly which program it was as I have since removed it.
Can someone help me identify the issue? Is it a Certificate Authority or DNS issue? I would love to get this solved...
Thank you!

mdkat, I have encountered this problem in the past, and doing the following helped:
In the URL, simply lop off the "s" at the end of https:// and load the resulting URL.
Before you quite understandably jump on me to say that this action will result in a non-secure connection, confirm for yourself that this will result in the web page being reloaded with the proper https:// protocol with the secure SSL/TLS layer as well as the feel-good lock icon.
That is not to say this behaviour is correct. Obviously the warning you see is an indication Safari / Firefox and the site you're accessing are not communicating in some way, but fixing it is up to them.
Use as you see fit, as I say it works for me.
I should mention that at one point I had a scan/clean app installed. Before this app was installed it seems to work, however, I can't directly link the timing. I can't remember exactly which program it was as I have since removed it.
Good idea. Probably not related though, since I have never installed such things.
... and thank you for writing such a thoughtful and well-organized question!

No guarantee but try tapping Settings / Safari. Clear the History, Cookies, and Cache. Restart the iPad.

Reset Safari -- Now I Can No Longer Access Secure Sites Or iTunes Store.

Hi, A few days ago I reset Safari (I'm still not sure why... boredom??). Well, now I'm paying for it. Now I can't access secure sites (such as gmail, bank accounts, etc.). in Safari. When trying to access a secure site I get an error window that reads something along the lines of: "Safari can’t open the page because it couldn’t establish a secure connection to the server." Even more annoying, I can't access my account on iTunes or access the iTunes store. When trying to do so an error window pops up that reads: "iTunes could not connect to the iTunes store. The requested keychain was invalid. Open keychain access and run Keychain first aid, then try again."... Did all that. No help. Incidentally, all my keychains are now gone).
I tried accessing the secure sites through Firefox, which still works fine. But the iTunes problem persists no matter what.
Has anyone else been encountered these same problems or know what I need to do to fix them? Any advice would be appreciated. I'm stuck!
Thanks in advance!

Still having this problem - is there no one out there who can help me? Surely someone must have had this happen before, no? You're all making me feel really stupid!!

Safari can not access any secure (HTTPS) web pages

Does anyone have an idea why a good frined of mine using Safari 1.3.2 on a Power Book G4 with Mac OS 10.3.9 can not access any secure web pages (those that start with HTTPS)? I can not find any preferences that might control this. She can access the pages with IE but not Safari. What setting on her computer might control this? Any ideas would be appreciated. I even through away (com.apple.Safari.plist) file. Not change. An ideas??

I have the same problem! However, this is ONLY while running wireless internet. Anytime I want to use an HTTPS site, I have to plug directly into my router, so I'm not wireless anymore, and then it works fine. Every now and then (like maybe 5% of the time), I get lucky and it will work for a short while such as logging into yahoo mail for example (logging into here didn't work at first but after waiting a bit, i was able to log in), but trying to stay on a secure connection such as a bank accnt. is impossible.
Any help would be GREATLY appreciated! Everyone I've asked says they've never had the problem. I thought I was the only one.
I checked my proxy settings -- nothing is checked. I've tried deleting preferences and I reset safari often.

Safari can't open specifics web sites

i'm having troubles to re-open some web sites visited earlier.
I'm on a macbook pro with leopard and safari 5.0.1, all updates installed
Example: www.tgcom.it
The first time opened without any problem, the second time can't open again.
after typing the address and hit the return key, safari display immediately (without even trying to load the page) the white page with the alert:
Safari can't connect to the server.
Safari can't open the page “http://www.tgcom.it/” because safari can't connect to the server “www.tgcom.it”.
I've try already to reset Safari and clean the cache. No changes.
On the same network I have an iMac, which is loading this page anytime without any problem.
As well a windows PC is on the same home network, the page can be loaded too.
Only on this macbook pro i'm experiencing this issue.
I don't know what to think more..... the problem can't be the web-site (it works with other machines)
Other web sites on the macbook are working properly, only three address seams to be blocked from this machine only....
any suggestions???? thanks
Marco

I suspect it has something to do with your ISP.
Adding Open DNS codes to your Network Preferences, should give good results:
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:

Can Safari save name/password for secure sites?

I use several webmail links several times per day where I have to enter account name and passswords. These are long strings with lots of numbers and symbols. Lots of opportunity for typos.
Is there some way for Safari to save name/password for frequently visited sites?

There is an App called 1Password (paid) that does save passwords, etc. and will automatically enter them in its OWN browser but not Safari. Sorry to say, I have only read about it and not tried it - didn't like the idea that it was a separate browser. But unfortunately, how the OS works, Apple will not allow 3rd party apps to run in the Background, thus allowing the integration with Safari.
Hopefully Apple will address this in future versions. Something like the Keychain App in the Mac OS, that holds all you passwords, but I think they won't because it means that if you lose your phone and someone finds it, then they will have access to whatever you have password protected.

Can connect to two secure sites

I've done some reading on threads where people have trouble connecting to selected sites, but I don't think those solutions apply with this situation.
I went to a friends , mothers house, to help here with getting her new flat panel iMac on the web correctly and to get her PC laptop on the wireless router that her ISP provided. She had been talking to tech support for some time, and he finally got her partly working, but not everything worked as it should.
I got her PC and router working but I was stuck with her Mac situation. She has two sites she visits to pay bills. A bank and (as some of the threads also listed ) DirecTV.com. She can get to the sites, but once she tries to login and the address is https: ..... rather than http: the browser stalls. I tried FireFox as well. Same result. I reset Safari. No dice. I even created a new user account, to get a new set of user preferences. No change. Her PC can get to those pages just fine, using the same router, on the wireless side. I tried tossing a few of the security prefs and that didn't change things. I verified nothing was set in her firewall, and even turned it off.
Here is the kicker... while I was doing this, and she recounted what the tech support guy did, over the phone, as he remote controlled her machine, she mentioned that at one point, she could ONLY get to those two sites, and now they are the only two she can't get to. I suspect he may have been trying some settings, asked her for two sites she goes to, and she mentioned WaMu and DirecTV. Maybe he put them in some DNS screen or host file settings ? I doubt the guy would know how, but you never know. There must be a global setting that might control this. I know it's not the router, or a web browser issue.
Any suggestions ?

She is going to a secure website that needs a certificate. Its information is in Safari Help, search under security certificates.
Same with Firefox where setting are under Advanced>Encryption

Safari can't display the security code

I was trying to charge my international calls account online but I noticed that Safari was unable to show the security code in the web site:
https://www.smslisto.es/en/login
I couldn't get it to show up until I used a PC with Internet explorer.
I tried to fool the website by going to the "develope" menu and choosing IE 10 as a user agent but that didn't work.
Any way around it?

Hi Claywd
I think you can help me without my account. You can click on "forgot your password?" and you will see a question mark which is actually supposed to be a security code. Please let me know if you can take a look.

Safari "can't establish a secure connection to the server insert website "

Per the title, Safari has started saying that it cannot establish a secure connection to the server. This occurs when I try to log in to any website.
I have reset Safari, I have turned my router off and on (I am using a WiFi connection).
I upgraded (today) to the newest software, Mountain Lion.
There is another Mac in the house (not on Mountain Lion) that works fine.
I downloaded FireFox and everything works fine.
I am using a Macbook Pro.
Fix, anyone?

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.

Safari can't find any web sites on hotel wifi?

Hi,
I have connected to the wifi service at the hotel I'm staying at but the only site I can get is google. If I type an address into the browser it says my computer isn't connected to the Internet, even though internet connect says I'm connected.
It did this at the last hotel I stayed at. Both my iPod touch and my wife's Archos can connect fine.
Is it likely to be a setting that needs changing on my Macbook?
Any help appreciated,
Thanks
Jono
