Cannot play flash behind corporate, Firewall issue?

Hi all,
I can play flash within a website when I am at home, but when
I get to work and plug into our network, the fllash on the webiste
does not play. Does anyone have the same problem? How do I fix
this?
We are using a Sonicwall Firewall 4060, but this should not
stop the content from playing...right?
Thanks

What version of Flash do you have, and what browser are you
usin?
Because both sites you mention work perfect for me (player 10
rc, IE7 & FF3) I am going to guess that you are using Internet
Explorer.
There is a problem that sometimes happens with the OCX
required to run the ActiveX version of the flash player. This
usually has the habit of not allowing people to properly upgrade
their player, or stops flash sites from working correctly. In Win
XP I typically go to C:/Windows/Download Program Files and delete
the entire folder to fix this issue. This folder holds all of the
OCX files that IE uses to run the various plug-ins you have
installed. By deleting the folder, you remove any corrupt files
that are in there, and IE will re-download the controls the next
time you open the browser, effectively fixing the issue.
This issue has become extremely prevalent with player 9, and
Adobe increasing the web install method to install the
player.

  • Flash behind corporate Firewall/proxy

    Hello,
    I work for part of the NHS in Scotland.  we are having issues with some flash content, bbc news website being an example.  We proxy all requests, and the bbc website flash content isnt being displayed.  My network guys have checked the proxy logs, and we see a direct connection out to the internet, which fails at the firewall.
    From what I read, this is normal for flash, that it doesnt use the system proxy settings.  Whats confusing us is that the proxy logs show in some cases a direct connect request which fails, followed by a request for the same content via the proxy. 
    I'm trying to explain to customers why we cant get certain content, and the above seems inconsistent. 
    Is anyone able to explain the above behaviour?  Why does some content pass via the proxy, and some fail?
    Many thanks.
    Scott

  • Cannot play Flash video in Chrome 64bit

    I cannot play Flash videos in Facebook when I upgraded my Google Chrome on Windows 8.1 to the latest 64bit v.37 and Flash player to v.15 . The error message was "Can't load plug-in". I enabled Flash players in the plugin section, reinstall Chrome. Nothing worked until I "downgraded" my Google Chrome to 32bit. Any help is appreciated. Thank you.

    Rebooted Windows and it is working. Note to self : It is good to reboot the system after a few weeks.

  • Renew activation error behind corporate firewall and proxy

    Hi all,
    I have come to the end of my first month for CC subscription and have been getting the following popup saying that my subscription (to CC) has expired and unable to connect to the internet.
    I have followed all the step by step instructions at http://helpx.adobe.com/x-productkb/policy-pricing/activation-network-issues.html with no success.
    My computer is on the corporate network and has both a local firewall and a corporate firewall and proxy. According to our IT HelpDesk, the local firewall is not the issue, and they suggested asking here in the Adobe Forums for advice on how to make this work.
    I also tried clicking the Subscription Manager link in the popup, but it doesn't take me to any page where I can activate the CC applications. Is there a way to manually activate them? I will have access stopped by Monday and I need continued use of the applications.
    Any help would be appreciated.
    cheers, Pete

  • Cannot play Flash content in IE7

    When I navigate IE7 to any site (including adobe.com) that
    has Flash content, I get a message saying I need to enable
    javascript (it is) and/or upgrade my Flash player. I am running
    Vista, and this worked until sometime in the last week or so.
    Flash content does run on this machine inside Firefox 3.0.1,
    but IE7 appears to be dead.
    The error message I get is "Error in loading DLL". It appears
    to pop up when the javascript code is trying to load or access the
    flash content.
    I tried installing the Flash Player 9.0.124 using the web
    site - no luck.
    I tried uninstalling (clean), rebooting, then installing from
    the web site - no luck.
    I tried uninstalling (clean), rebooting, then used the manual
    installer (Install Flash Player 9 AX) - no luck.
    I tried uninstalling (clean), rebooting, then used the manual
    installer (FlashUtil9f) - no luck.
    I tried running reset_minimal.cmd (per instructions) - no
    luck.
    I tried disabling my AV (Kaspersky) while repeating all of
    the above - no luck.
    I tried running sfc /scannow but it reports no errors.
    I tried the Tools/Internet Options/Advanced/Reset to "reset"
    IE to its defaults - no luck.
    I am really, really stumped on this one. What should I do
    next?

    BWolfe, dougclutter, and others with Doug's problem:
    BWolfe, I'm truly amazed that dougclutter and others have had
    this very specific and real problem for so long, and Adobe hasn't
    lifted a finger to cure it. I'm stunned. I've been plagued with
    this thing for at least 3 months now, and have been all over the
    net looking for a remedy, after finding absolutely no help from
    Adobe.
    Here's what my symptoms are:
    IE with Flash works in all accounts but mine.
    Latest Adobe Flash player (10) is properly installed. Flash
    content will play on IE8 in anyone's User Account on this machine
    but mine. The only way flash content will play in my user account
    is if it is started as "Run As Administrator". Can actually run 2
    instances of IE side by side, one started normally, the other
    started as "Run as Administrator". Oprah, U Tube, etc., will run
    flash content in the latter window, but won't in the former. Flash
    errors (in IE7} are something to the effect, "Can't run DLL", with
    line number reference, etc. No help from Adobe, HP (my machine
    manufacturer) or Microsoft without paying them a bundle. Just
    updated IE7 to 8, problem unchanged.
    Elaboratiing:
    When right clicking on where Flash Player is supposed to be,
    then clicking the "about Adobe Flash... ", the browser is sent to:
    http://www.adobe.com/products/flash/about/
    When clicking on the error message at the bottom of the
    browser, the following error message is displayed. (This was
    copied, which Vista gives you the opportunity to do, then pasted
    here.)
    Webpage error details

    Flash content DOES play with Adobe Flash 10 in my user
    account with Apple Safari browser when started normally, just not
    with IE8 browser. However, the IE8 browser does play Flash content
    in any and every other user account.
    BWolfe, instead of telling us about proper Adobe procedures
    for reporting and troubleshooting these things, how about you
    forward this to someone who can tell us how to fix this thing! I,
    like dougclutter and others, have been thru the entire Adobe Flash
    Player troubleshooting guide, carried out every suggestion there
    exactly, to no avail. I can show you at least 3 other instances of
    different folks with this same problem. And, as I think I've seen
    elsewhere in this thread, and tried myself, Adobe certainly doesn't
    make it easy to report non-paying customer problems, as with Flash
    Player.
    It's high time Adobe gets with at least one of us to help
    diagnose and cure this problem, and then adds the info to their
    troubleshooting guide, or else fix it in the application if
    possible. Whether the problem is in the app, or do to interaction
    with Vista and possibly XP, you guys need to look into this thing.
    I, for one, would be more than happy to help you 'shoot this thing,
    I am and engineer and have been computing since the DOS days.
    Bewildered,

  • Cannot play Flash on sites

    I have a new Toshiba PC laptop using Vista. Though I have
    Flash installed I have problems playing it. The message given is:
    "You do not have the correct version of the flash player.
    Download the correct version"
    When I follow the instructions, I end up with exactly the
    same problem. I have followed the instructions given on the Adobe
    self help section in that I have uninstalled, cleared all old files
    and re-installed after rebooting but to no avail. I have also gone
    into the Windows/System32 section and run it from there - still
    nothing. I have checked my Firewall and Anti-virus (and even tried
    with them switched off) but still nothing.
    In the www.bbc.co.uk website it will not play videos (the
    message given above shows). In the www.landrover.co.uk site I can
    do nothing at all after the first page as it asks me to install
    Shock player (again with the same result). On www.youtube.com I can
    get the videos to play but cannot enlarge to full screen.
    I have written to a number of forums but have only had the
    official answer given on the Adobe site and since I have tried all
    of that I am now at a complete loss.
    Can anyone help?

    Hi!
    You can use Firefox 2.0 or 3.0. It will sold your problem.
    If you want use IE7, you need change something.
    You have to make changes to the Player.html files for each session
    1. Open the player.html file in notepad
    2. Add the following line right below the line that begins "var IE6 = ((...":
    +var IE7 = ((document.all)&&(navigator.appVersion.indexOf("MSIE 7.")!=-1)) ? true : false;+
    This will set the player.html page to check for IE7.
    3. Select Edit>Find in notepad and search for 'IE6' without the quotes
    4. You should find a couple of lines of code that have the term IE6 in them. They will look something like this:
    if (IE5||IE6||FF1) {
    or
    if(IE5 || IE6 || FF1){
    5. Add '|| IE7' to these lines, so they should look something like this:
    if (IE5||IE6||IE7||FF1) {
    or
    if(IE5 || IE6 || IE7 ||FF1){
    6. Save the file

  • Nokia Maps online doesn't work behind corporate fi...

    Hi,
    Nokia Maps online 'search' and 'routes' don't work on my work computer. My PC is behind corporate firewall and proxy, but that shouldn't be a problem.
    On my work's PC, I can save, edit and rename Favourites; I can rename Routes; I can see a route previously saved on my phone. But it's not possible at all to search for places and consequently it's not possible to calculate new routes.
    I think Nokia should pay attention to this proxy issue, if it wants Nokia Maps to become popular all over the world, since at least on my corporation, Nokia Maps is the only mapping system that cannot be used!
    Google Maps, NAVTEQ.com and TomTom route planner are some mapping systems that work fine on my work PC. Unfortunately, I cannot use Nokia Maps, which is my favourite system...
    Can a Nokia representive forward this to the Nokia Maps online team?
    Regards.

    I'm experiencing this same issue. Please fix it. Now I have to use google maps.

  • Cannot install any apps from Creative Cloud in corporate environment.  Suspsected Firewall issues.

    Hello all. 
    I subscribed successfully and easily to CC on my home PC (iMac) and downloaded a few apps.  All is fine. 
    I wanted to download those same few apps on a remove machine I use several times a week (Win 7).
    After many many attempts of trying to download CC and getting a generic error message, I learned it could be a firewall issue here at this work/office. I found this in Adobe's forums:
    Many organizations use a hardware firewall and proxy server that can prevent software from accessing an FTP server. A hardware solution applies to all computers within the corporate network. Most home networks do not use hardware firewall or proxy technology. 
    Contact your company's IT department to obtain firewall or proxy information.
    Configure your browser with proxy or firewall information.
    Configure your corporate firewall to by-pass the servers. The following servers are accessed:
    ccmdl.adobe.com:80
    swupmf.adobe.com:80
    swupdl.adobe.com:80
    Having nothing to loose, I put in a request and had these addresses/ports opened up in our firewall.  That seems to partially fix the problem.
    Now the problem is the speed and traffic is so terribly slow with CC that nothing installs with out failing and giving error. For example, I am trying to install PhotoShop CC and it will take a couple of HOURS to even get to 10% and then it fails.  Usually, it doesn't get that far.  CC just gives me the generic message:
    "Installation Failed - Learn More."
    Download error.  Press Retry to try again or contact customer support.(-7).
    Our network admins swear that there is nothing wrong with the ports/firewall and yet all this works fine at my home.  Can anyone offer any suggestions or advice?  My internet connection here is fine.  All other sites load and work fine.  I simply cannot download any of the CC aps here with any reasonable speed.
    Help!
    PS - The URLs and ports ping just fine.

    Hi RedBirdOBX1,
    I'd recommend checking out the two pdf documents in the
    Adobe Creative Cloud Service Access Documentation for IT section on this page:
    http://www.adobe.com/devnet/creativesuite/enterprisedeployment.html

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.

  • Safari cannot play certain flash videos

    After the latest update safari cannot play some flash videos, it can be a youtube video as well...
    There's a hungarian site that has videos and my safari cannot play any of them. The site is www.indavideo.hu . On a MacBook Air the Outlook cannot open new mail and a Microsoft community site said that it is a problem caused by safari... What?
    I've tried to delete flash, reinstall it, delete Java, reinstall it, but Java works fine.
    I think I should reinstall Safari, but I don't want to reinstall the whole computer...
    Does anyone have any idea?

    For Flash issues, try this ...
    Open System Preferences > Flash Player then select the Advanced tab.
    Click Delete All under Browsing Data and Settings
    Back to Safari. Press Command + Option + E to empty the Safari cache.
    Quit and relaunch Safari, try a video.
    If that doesn't help, you may have the YouTube HTML5 beta enabled.
    Opt out here >  YouTube
    Keep in mind, Outlook is a Microsoft product, not Apple and therefore, you may experience problems. However, you may be able to setup your Outlook account in the Mac Mail app.
    Open Mac Mail. From the menu bar click File >  Add Account
    That way you won't have to use Safari (web based email) to access your Outlook acocunt.
