OS X Lion access only HTTPS sites

Following latest (this past week) security update to OS X Lion, my browsers (both Safari and Firefox) will access only httpsaddresses, not http.   On my IPad, under IOS 7, and using the same network and service provider, I am able to access all Internet sites with no difficulty.  Is anyone else experiencing the same problem?

  • Cannot access any https sites, clock is OK, get This Connection is Untrusted error message.

    All works OK on Chrome and IE, but Firefox just suddenly stopped access to https sites yesterday, e.g. Google, Facebook and Linkedin. Non secure http sites are OK though. "This Connection is Untrusted" is the error message and technical details are www.google.com.tw uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer). I've tried all the Mozilla support suggestions, clock (which was always correct), reset Firefox, etc. No change so far, I hope you can help fix this issue.

    Check the date and time and time zone in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
    Check out why the site is untrusted and click "Technical Details to expand this section.<br>If the certificate is not trusted because no issuer chain was provided (sec_error_unknown_issuer) then see if you can install this intermediate certificate from another source.
    You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
    *Click the link at the bottom of the error page: "I Understand the Risks"
    Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
    *Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
    You can see more Details like intermediate certificates that are used in the Details pane.
    If <b>"I Understand the Risks"</b> is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
    *Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.
    *Note that it is not recommended to add a permanent exception in cases like this, so only use it to inspect the certificate.

  • I get an Invalid Certificate notice when I try to access my https site for my printer. The serial number is the same as used by another certificate. In IE I was able to proceed to this address, but Firefox won't give me that option

    Hello,
    Thanks for contacting Mozilla Support!
    Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache.
    Note: ''This will temporarily log you out of all sites you're logged in to.''
    To clear cache and cookies do the following:
    #Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
    #Under "Time range to clear", select "Everything".
    #Now, click the arrow next to Details to toggle the Details list active.
    #From the details list, check ''Cache'' and ''Cookies'' and uncheck everything else.
    #Now click the ''Clear now'' button.
    Further information can be found in the [[Clear your cache, history and other personal information in Firefox]] article.
    Did this fix your problems? Please report back to us!
    Thank you.

  • I am trying to access an https site and am getting a "This connection is untrusted" message. I am willing to bypass, but when I click the Add Exception button and then try to click the Confirm Security Exception button, nothing happens.

    unfortunately the do_not_trust certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.

  • Can LabVIEW access an HTTPS site behind a proxy?

    I have been trying to use LabVIEW to access an https site through our corporate firewall/proxy and have been unable to get it to work. Does anyone have any experience with this and or know whether this should be able to be done?
    I have successfully been able to get LV to access websites (http and https) without going through a firewall and thanks to posts on these forums figured out how to access an http site through the firewall but have come up blank when trying any https sites. Below are some test cases I have tried. All of these sites are easily accessed via browsers so it isn't due to firewall/proxy iblocking.
    Any help would be appreciated,
    -- Harold
    Solved!
    Go to Solution.

    I suspect the SSL handshake failing is getting close to the source of the problem.
    We have the same proxy port (8080) for both http and https as far as I can tell. I have used wireshark to monitor the message flow and LV is doing something quite different than my browser does.
    The browser opens a connection to the proxy (on port 8080) and then issues a CONNECT command to the proxy to access the ultimate location and then does a SSL handshake. 
    LabVIEW opens a connection to the proxy but then appears to be encrypting it immediately without a SSL handsake that I can see. 
    My speculation is that the underlying LabVIEW code is not really proxy aware and doesn't know how to issue a CONNECT command or equivalent. I'd be glad to be proven wrong with someone demonstrating this works for them (I've posted a sample VI in a previous post).
    I can also post the wireshark message info if it would help anyone troubleshoot what is going on.

  • Suddenly my TC network only permits access to HTTPS sites- all HTTP sites say "safari can't connect to internet"

    This morning my TC wireless network suddenly does not allow any devices on it connect to HTTP sites. "Safari cannot connect to the internet"
    My OS X 10.9.5 Mac email works, as does GMAIL and Yahoo mail apps on smart phones on the TC network, but none of the devices behind the TC network can access regular websites.
    What's interesting is that the other wireless network in the house (the one we use for guests) does work on HTTP sites. This router is plugs into the same cable modem as the TC.
    I've recycled everything, and did a hard reset on the TC, but to no avail. Any ideas?

    You have the TC setup wrongly .. it should be in bridge.. it sounds like you have it in double NAT.

  • Trouble accessing secure (https) sites

    I recently installed Leopard and upgraded to 10.5.1.
    I am now having trouble accessing most secure sites. I've tried the following:
    -Used different browsers (Safari, Firefox, Flock)
    -Emptied the cache (on all browsers)
    -Turned off the Mac OS X Firewall
    The problem persists on different routers/ISPs and I am able to access the site using a different computer (running Windows XP) on the same connection.
    Again, it is most connections on secure servers, but there are odd exceptions (such as logging into this discussions forum).
    I appreciate your help.

    The browser will immediately display a message stating that it cannot connect to the server, such as:
    Safari can’t open the page “https://online.wamu.com/” because it can’t find the server “online.wamu.com”.
    Other sites that give the same error:
    https://store.apple.com/
    https://login.byu.edu/
    It shouldn't be a server related problem since I can access the same sites from other computers running Windows or Leopard on the same or different connection.

  • Can't access ANY HTTPS sites, and problem affects only one user acct !

    My new iMac (arrived yesterday) is driving me nuts, getting me sick. Countless problems ... def. not the experience I was hoping for ... (I'm not a new mac user, own a macbook for 3 years now).
    The last one is that my account, for some unknown reason and all of a sudden (was perfect before), stopped working with ANY HTTPS connection ... banks, whatever ... anything that involves a secure protocol is out. I can't even login to my iTunes store. The message is that it can't estabilish a secure connection to the server. (Oh, the iTunes reports unknown error, wich took me 2 hours to find out that it wasn't iTunes fault, but the whole system was not working with HTTPS).
    I already tried reparing the disk permission, verifying the disk (no errors found), AND reparing the keychain using the keychain aid. Oh, I also reseted Safari ...
    The weirdest part of it all is that another account I had set up on the iMac works just fine. JUST FINE. And my main account is hopeless.
    Does ANYONE have any clue on this ?
    (btw my new iMac just screwed my iPhone on the first sync ... it was supposed to go smooth since it was set up using a time machine backup from the macbook .. but no, it erased half of my apps in the iphone, including my task managing apps with LOTS of scheduled to dos ... this is ridiculous).

  • No email download, can access only secure sites

    I have a weird problem.
    I have a 2010 MacBook Pro with 10.6.8 updated on all Apple apps. I started not being able to access "normal" websites (http://....). However, I have no problem accessing secure sites (https://....). I also have the same problem regardless of browser (Safari, Chrome, Firefox). I also am not able to download any email to "Mail" app (tho thankfully am able to view it in my Spammarrest account--a "secure" site). I backed up my hard drive, repaired permissions, verified and repaired disk (got one message that originally said "The volume...was found corrupt and needs to be repaired."). Repaired permissions. Have since run Verify (in Disk Utility) and three times it shows "OK".  Does anyone have ANY ideas?  I think it must be software related, perhaps doing with permissions (have reparied permissions twice).
    My wife has no such problems on her iMac, so likely not router related (of course, I have rebooted everything several times).
    Thanks anyone!

    The problem is not solved yet.
    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal 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. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' 
    Copy (command-C) the selected text to the Clipboard. Then click anywhere in the Terminal window and paste (command-V). Post the lines of output (if any) that appear below what you just entered. You can do that by copy-and-paste as well. Omit the final line ending in “$”. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}' 
    This time you'll be prompted for your login password, which you do have to type. It won't be displayed when you type it. Type it carefully and then press return. You may get a one-time warning not to screw up. You don't need to post the warning. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}' 
    Step 4
    ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • Can't Access Secure (HTTPS) Sites On One Account, FF or Safari???

    Hello Mac Fans
    First let me say I'm new to Mac. On one account I can't access secures sites like I can in the admin account. This may be a function of rights but am not sure? All updates have been done.
    I can't login to this forum, my MobileMe account or my bank for example. I had to change to my other account or gasp, use a PC to post this message.
    I installed FireFox trying to isolate the problem to Safari but that didn't pan out, I can't get to HTTPS pages in FF either.
    I turned off Little Snitch thinking I might have denied something by mistake but that didn't help. I checked the rules and found nothing that wasn't allowed.
    Nothing was changed in the router. I just turned on Mac and it worked. The iMac is connected to the router via ethernet cable.
    I've used the search function and tried a few things that have been recommended for others but they didn't help me. I went to the keychain and did a repair, although it didn't find any problem. I over rode a couple keys to always allow them (Apple site stuff) and I ran the disk utility to no avail.
    For reference I will post the information for both Safari and FF.
    Safari:
    Safari can’t open the page “https://support.apple.com/cgi-bin/WebObjects/ACAuthWeb.woa/wa/login?
    appIdKey=2ddbca23a85d20e5bf7478812379ae23&path=/login.jspa%3FsuccessURL%3D/index .jspa” because Safari can’t
    establish a secure connection to the server “support.apple.com”.
    Safari can’t open the page “https://www.mln'sbank.com/” because Safari can’t establish a secure connection to the server
    “www.mln'sbank.com”.
    Safari can’t open the page “https://auth.apple.com/authenticate?service=DockStatus&realm=primary-
    me&returnURL=aHR0cDovL3d3dy5tZS5jb20vd28vV2ViT2JqZWN0cy9Eb2NrU3RhdHVzLndvYS93YS9 0cmFtcG9saW5l&destinationU
    rl=” because Safari can’t establish a secure connection to the server “auth.apple.com”.
    FireFox:
    The connection was interrupted
    The connection to support.apple.com was interrupted while the page was loading.
    * The site could be temporarily unavailable or too busy. Try again in a few
    moments.
    * If you are unable to load any pages, check your computer's network
    connection.
    * If your computer or network is protected by a firewall or proxy, make sure
    that Firefox is permitted to access the Web.
    I've done a lot of snooping around on this forum and have ran out of ideas so now I must ask for help.
    Thanks

    I think I may have found the problem. It's embarrassing to find it minutes after posting the message yet I tried to solve it off and on for three days! My brother who is a 20 year Mac user has been trying to help me too. I guess it's true what they say... sometimes it's better to be lucky than good. LOL
    I turned off the parental controls. What I don't understand is that the no website restrictions box was checked. To me this means I should be able to go to any site I wanted. Can anyone explain why I couldn't got to a HTTPS page on a parental controlled account even though there were no restrictions placed on it?
    It's late and I need sleep. I'll leave this open for now until I have more time to test it.

  • Firefox suddenly stopped allowing access to Https sites, saying the sites are untrusted. Chrome and ie allow them. What's up?

    Windows 7 64 bit
    ESET antivirus
    The sites in question are all sites that I've used frequently, they are trusted. When I read the details on the warning page at least one site had a valid certificate based on the dates. The reasons given are not all "expired" there are several others. Here's another example:
    www.bankofamerica.com uses an invalid security certificate.
    The certificate is not trusted because no issuer chain was provided.
    (Error code: sec_error_unknown_issuer)

    Some firewalls monitor secure (https) connections and send their own certificate instead of the website's certificate.
    You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
    *Click the link at the bottom of the error page: "I Understand the Risks"
    Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
    *Click the "View..." button and inspect the certificate and check who is the issuer.
    You can see more Details like intermediate certificates that are used in the Details pane.
    Some examples are ESET and Bitdefender.
    *ESET setup -> advanced setup -> extend web and email tree -> SSL
    *SSL protocol: Do not scan SSL protocol

  • Firefox can access HTTPS but not HTTP sites

    Hi,
    All of a sudden last Friday afternoon I could not load any sites external to our corporate network over HTTP in firefox; HTTPS still works fine. Also IE doesn't have any problems.
    So far I've tried uninstalling and reinstalling, creating a new profile, disabling IPV6, disabling DNS prefetching and checking my firewall settings. I've also used wireshark to try and see what firefox is doing, but it seems that no traffic at all appears when an HTTP website is accessed, however accessing an HTTPS site does generate traffic.
    We use Windows firewall with advanced security; I can't change much though because it is controlled by policy.
    We also use McAfee for antivirus and Bluecoat for filtering; again I can't change anything here because they are either policy controlled or administered from elsewhere.
    I think I can rule out Bluecoat as other PC's on our site can and still are using Firefox 4 to access the web.
    Any help would be much appreciated.
    Many thanks
    Matthew Rose

    Two different sites, one with .info and one with .net.  One works perfectly without issue and they each have similar settings in Server, however one only seems to want to work using https prefix.  The sites are both different and therefore needs to be accessed with http at this point.  The problem is when I go to http://example.info it takes me to http://example.net which is not what needs to be occuring.  This occurs internally and externally.  Before the move I did my server was doing DNS as well and those settings have not changed or been modified except when I had to change their outside static IPs.
