Unable to access SSL Web site when company proxy use man-in-the-middle attack to scan SSL traffic

Our company uses a proxy server that analyzes the SSL traffic on web sites. This is done via man-in-the-middle attack. The proxy generates a new certificate on the fly that it sends to the client, impersonate a secure server.
After upgrading from Firefox 10.0, I always get error:
Error HTTP Status: 400 Bad Request
After the confirmation of a security exception.

Maybe this is related to the difficulties of the attack of the BEAST bug (browser exploit against SSL/TLS)

  • Urgent - unable to access some Web sites through Time capsule

    I have been using Airport Extreme for years and the wifi connection has been perfect. But since there are days, if my Mac, PC or mobile devices, I started to have problems connecting to a couple of pages of Weebly, I built for work. Access to other Web sites are still as smooth as ever. I tried to restart my Airport Extreme updated Airport Extreme software in Airport utility, but not luck. Please inform how I can solve this problem. Thank you very much!

    It seems logical to blame the airport Time Capsule, but please read the link below for more details know why things can't be like you think they are.

  • Why can't access Web sites when I copy & paste or type the address in the address window - no answer - but I CAN visit Web sites non - Firefox only?

    I can access websites through bookmarks, most visited, history or if I click on links in Google, etc. If I click on a link directly, it will open. If I copy & paste or type a link into the address window, click Enter or on the arrow "go to" in the address window - no response. I tried several Web sites. This seems to have happened since the 29th of Firefox upgrade. This only happens with Firefox.

    You can try to start Firefox in Mode safe to see if Firefox works correctly without error? You can start Firefox in Mode safe below:

    • Windows/Mac: choose Help > restart with disabled modules
    • Linux: run firefox-safe-mode in the Terminal/Konsole

    If Firefox opens fine with no problems, it is probably one of your extensions that is causing the problem. You can reactivate your modules one by one until you find the one that is causing the problem to be re-activated.

    This might or might not be relevant to your question, but it seems that user.js is currently active in Firefox. The user.js file is present than if you or another software has created this file and normally it wouldn't be here.

    You can delete a possible user.js file and numbered prefs-# .js files and rename (or delete) the file prefs.js to reset all the prefs by default, including the prefs set via user.js and pref which is no longer supported in the current version of Firefox. You can get the profile below:

    • Help > troubleshooting information > profile directory > see folder

    or

    • Go to Subject: support , and then click view the folder next to the profile directory.

    I can't access a website, I used regularly - www.chainreactioncycles.com--de this PC under XP SP3.  I get an error "Internet Explorer cannot display the website".  The problem is also in Chrome (Oops! Google Chrome could not connect to www.chainreactioncycles.com) and Firefox (the connection has expired).

    Other PC and Android devices on the same home network work fine, so it seems not to be a Web site problem or the DNS server.  I tried a few reboots and cleared out the local DNS cache with "ipconfig/flushdns" but the problem remains.

    Any suggestions?

    It could be related to firewall. Try disabling the firewall to test.

    Otherwise, open a command prompt and type: netsh winsock reset and press ENTER.

    Then restart and then try again.

  • Cannot access a Web site, but can ping IP addresses on the internet

    -With the help of Vista SP2 64-bit on laptop faulty.

    -Number of computers on the same network have access to the internet.

    -Tried several network interfaces on this laptop, but no luck for access to the network, wired or wireless

    -From this notebook, I can ping addresses Internet IP so the problem seems to be the side DNS.

    -Flushing DNS cache and reset the network interface.

    -Rebooted several times.

    What did I miss?

    Thanks in advance

    Hey easternguy,.

    Check if you can test the Web site by name.

    To do this:

    a. Click Start and type cmd.

    b. press ENTER.

    c. type the following command:

    ping hostname

    Ping uses name resolution to resolve a computer by IP address name. Therefore, if you successfully ping the IP address but you cannot ping a computer name, there is a problem with host name resolution, and no network connectivity.

    Case 1: If you can not ping the Web site using its address, follow these steps.

    In this case, try changing your host file.

    In the C:\Windows\System32\Drivers\etc Hosts files may be damaged or corrupted.

    Review the contents of your HOSTS file and compare it to the screenshot below. There is no need to worry about any line that starts with a # is ignored by Windows. In addition, the line "127.0.0.1 localhost" can be ignored without risk, because it is a standard input.

    Everything that appears in your HOSTS file without a # earlier this year, aside from the "127.0.0.1 localhost" line, should be regarded with suspicion when we try to diagnose the cause of the problem. The fastest way to test the involvement of HOSTS file is to just rename the host file. By changing the name of the HOSTS file, prevent us Internet Explorer to use it and so all problems caused by the file.

    Case 2:

    If you can ping external websites by IP address and name, but can't browse the web, probably your browser is misconfigured.

    Check that you do not have an incorrect Proxy Server affected necessary or not.

    For Internet Explorer, follow these steps.

    a. open Internet Explorer.

    b. go to Tools / Internet Options.

    c. click on the Connections tab.

    d. click the LAN Settings button.

    "e. uncheck both" "automatically detect settings" and "use a proxy server for your LAN '.

    This should be it.

    Kind regards

  • I get "unable to connect to web services" when trying to use them.

    I bought a HP Envy 114.  I've connected to the network and can not print from multiple computers without problem.  When you attempt to connect and allow web services he asks me to accept the terms, then 'check' of product updates.  He always comes up saying "unable to connect to web services.  Confirm access to the internet, and then try again. ».  I set up the wireless and it diesplays the network name and IP address.  I don't know what else to try at this point.  After that, there is no help, I just keep getting sent in circles.

    It took a couple times but it seems to work perfectly.  Thanks for your help.

  • Can't access some Web sites

    Original title: access to the problem Web pages

    I recently got roadrunner as my Internet service provider.  I'm unable to access any Web site other than the home pages of MSN & Yahoo.  When I try to access any other nested web site (i.e. Favorites) I get a can't connect message.  According to roadrunner, it's a problem of mircosoft software as their cheque for their system shows no problem.  Someone can help or should I get another ISP.

    Oh yes, I also have a hotspot to verizon as a secondary ability that I can use without any problems.

    4 did you do changes on the computer before the show?

    If you use Internet Explorer, while the issue may be due to some modules or settings. To check, I suggest you to refer to the section I can access some websites, but not all in the site:

    Hi Matt,

    This forum is for MSE who cannot restrict access of Web site you want.

    One of the possible methods that comes to mind uses the Parental http://www.windows-help-central.com/parental-controls-in-windows-xp.html may control with Windows Live Family Safety http://explore.live.com/windows-live-family-safety?os=other (according to the version of XP and whether or not you have a workgroup or domain LAN).  When you set up, allow *.gov, but reject all other types you can imagine (I don't think there is a way to allow only .gov, but you can exclude most if not all of the other busiest - check domain name registrars to get a list of options).  If you use a domain, way to go would be with a custom domain group policy to restrict access on all of the network (except perhaps the server or individuals of special category in Active Directory if you want).

    If that is not the case, and I think it might, please repost your question in the following forum to get the expert assistance you need: http://answers.microsoft.com/en-us/windows/forum/windows_xp-networking?page=1&tab=all.

  • What is missing when I get a white screen empty when I try to access certain web sites?

    On some websites, I get a blank white screen when I try to access it.

    You can try the following steps in case of problems with web pages:

    You can reload webpages and ignore the cache to refresh potentially stale or corrupt.

    • Hold down the SHIFT key and click the Reload button
    • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
    • Press 'Command + shift + R' (Mac)

    Clear the cache and delete cookies only from Web sites that cause problems.

    "Clear the Cache":

    • Firefox/tools > Options > advanced > network > content caching Web: 'clear now '.

    'Delete Cookies' sites causing problems:

    • Firefox/tools > Options > privacy > "Use the custom settings for history" > Cookies: "show the Cookies".

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

    • Put yourself in the DEFAULT theme: Firefox/tools > Modules > appearance
    • Do NOT click on the reset button on the startup window Mode safe
  • FF8 + dialog box popup "application/vnd.wap.xhtml+xml" when you access a Web site.

    FF8 cannot use the www.translink.com.au trip planner.

    When I fill in the fields and click on 'Find journey' - a dialog box appears

    "You have chosen to open the trip planner.
    which comes from application/vnd.wap.xhtml+xml a: (27.6 KB): http://jp.translink.com.au
    What should Firefox do with this file?
    Opened with Browse...
    Save the file.

    Also a few other buttons on this site do the same thing, for example. On this page and train travel planner:
    http://TransLink.com.au/travel-information/services-and-timetables/buses/Route-204
    -If you click on the button 'Show time' - it does the same thing.

    This site worked before ok with FF7 and IE8.
    A release with the troubleshooter from the site Web - no response.
    Now it is unusable and don't know what to do.

    Other than this problem only seem to work ok - FF8 so this Web site is to blame?

    Googled the problems forums and looked for a solution - it's a problem similar to mine:
    http://support.Mozilla.com/en-us/questions/796303?s=application%2Fvnd.WAP.XHTML%2Bxml & r = 1 & s = ACE

    PS - to confirm - I use a desktop pc with a mobile broadband usb dongle.

    I hope someone can help.
    Thanks in advance.

    "FF8 + dialog box popup"application/vnd.wap.xhtml+xml"when you access a Web site."

    THE PROBLEM ABOVE IS NOW COMPLETELY RESOLVED.

    The site in question was the problem - NOT 8 Firefox or Linux Mint.

    The site has been fixed and now works as it should.

    If someone else gets a dialog box pop-up similar box to the above - suggest that they contact the administrator of the website the problem and inform them that their site user agent detection Web is not correctly identify your version of Firefox mobile browser and so redirecting to a mobile version, return of mobile specific markup (Content-Type).

  • I just upgraded to Firefox 5.0.1 and because the "padlock" icon never appears when you access secure Web sites, where should I look for it?

    I recently upgraded to Firefox 5.0.1 and now the 'lock' icon is nowhere (I don't know) when you access secure Web sites. I've not seen once. It appeared in the lower right of the screen. I also have Norton Internet Security.

    Well, in the secure Web sites part of the address bar is allocated to the part of the security certificate. For example, here in these forums you can see your address bar is as follows: mozilla.com . https://support.mozilla.com... The front ' |' ("mozilla.com") is what I'm talking about. For more information on the security certificate, you can mouse over and also clicking on it.

    When you try to connect to Web Sites requesting my user ID when I try to enter it can't do.  The reason in

    that my ID is Alpha numeric. When I enter the Alpha which is OK. but when I add the digital all I get is Alpha?

    This only happens when you try to access a Web Site.  Microsoft Word works very well. In fact I can type my user ID in Word and copy paste into the connection site. Which works very well.

    It makes no difference as to what I use either Internet Explorer, Firefox or Google.  Please notify.
