Application Issue - Adobe connect unable to handle "unreachable" responses

Hi,
We've discovered what seems to be a bug with the Adobe Connect application/flash player.
For some reason when you have a proxy in place adobe connect still attempts to establish a direct connection to the adobe servers (for example na7fms2.adobeconnect.com), if these packets get dropped video plays with no issue.
However in our case we have ACL's setup on our Cisco routing core (which do not allow this traffic), which in turn respond with "Destination Unreachable (Communication administratively filtered)".
Adobe Connect seems to be unable to handle these responses and goes into a loop continiously attempting a direct connection (around every 10-12 seconds), therefore causing streaming video's to restart every 10-12 seconds.
Below is a screenshot of the packet capture of the accurance.
Basically we managed to create two of the following scenarios in our network.
Video restarts every 10-12 seconds:
Video plays with no issues:
Now this "Destination Unreachable" response is completely legal in terms of RFC http://www.ietf.org/rfc/rfc792.txt
It would be great if this issue could be raised as a bug and fixed in future versions.
Thanks,
Daniil

Seeing the same issue.    Did anyone find any solution?.
Only solution that I could see was opening HTTPS at firewall for only Adobe Connect servers.  Wasn't able to locate anything that published the network ranges for the Adobe Connect servers however.  Wasn't really a solution that I was happy with anyway.
Only need to do this to allow 1 employee to access a recorded Adobe Connect meeting.
Thanks
Iain.

    Thanks and regards
    Selvan

    OK, so it's a plain Flex security issue, not related to the Connect application, probably due to crossdomain misconfiguration.
    Please read http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html and http://www.adobe.com/devnet/flashplayer/articles/fplayer9_security.html
    You may want to ask for help in the proper Flex forum. Also, download Tour de Flex and look at the example under "Flex Data Access3 -> "WebService".

  • I Receive Error DF015 Unable to delete symlink "/Library/Application Support/Adobe/APE/3.4/adbeapeco

    Hi,
    I am having issues installing Extension Managger CC.  I receive the follwoing error when attempting to install Extension Manager:
    Exit Code: 7
    Please see specific errors below for troubleshooting. For example,  ERROR: DF015 ...
    -------------------------------------- Summary --------------------------------------
    - 0 fatal error(s), 1 error(s)

    ERROR: DF015: Unable to delete symlink "/Library/Application Support/Adobe/APE/3.4/adbeapecore.framework/Libraries"(Seq 4)
    I don't know if the permissions on the file (and contents) are correct.  I noticed that they were pointing to a user that no longer exists.  I manually went in and made the owner and groups point to system, wheel and root and everyone, with all three having R+W access.
    Are these the correct permissions?  I was thinking of using Adobe CC Cleaner but I didn't see anything that mentioned Extension Manager.  What would the APE 3.4 be called?
    What yould you recommend?
    Thanks,
    Rocky

    Moving this discussion to the Creative Cloud Download & Install forum.
    Rocky you are correct to determine this is a file permission failure which is causing the error.  Please see Error "Exit 6" or "Exit 7" | Install log | Read, write, system file errors | CS5, CS5.5 - http://helpx.adobe.com/creative-suite/kb/error-exit-6-exit-7.html for information on how to adjust the file permissions.
    If you continue to fail with this update you may want to try applying the update in either a Root user account or a new administrator account to see if the same failure occurs.

  • Video playback issue for Adobe Presenter 9 when publishing to Adobe Connect Pro 7

    Hello!
    I am having an issue with video playback for Adobe Presenter 9. When I preview the presentation on my computer there are no issues with any of the MP4 videos that I have loaded into my presentations. However, when I publish the presentation to Adobe Connect and access the URL the videos are either delayed or do not appear at all.  We are using our own Adobe server which we purchased in 2008, along with Adobe Connect Pro 7. We recently updated our Adobe Presenter software to version 9. Is there an incompatibility issue between Adobe Presenter 9 and our current Adobe Server/current version of Adobe Connect? Or do I need to do something different in Adobe Presenter when importing the videos?  Note: I have tried FLV videos and had the same issue.
    We are trying to launch of series of webinars (each webinar has between 15-42 slides), which was the whole purpose of updating our Adobe Presenter and Adobe Captivate software....hopefully we can resolve this video issue.
    Thanks!
    Dana

    Connect 7 didn't support MP4 video content, as I recall. Another issue is that Connect rooms are using Action Script 2 (AS2) while Presenter 9 uses AS3, and the two code languages don't play well together. You don't mention if you are using the meeting application to display the presentation, but it is worth mentioning. If the presentations are stand alone, then the AS3 issue should be non-existent, but the MP4 support may be.
    Is there a reason you haven't updated the Connect software to Connect 9 (or at least Connect 8.1 where the Connect application became AS3 as a whole and supported MP4 content)?

  • Adobe Connect Mobile issues on Motorola RAZR

    While trying your Adobe® Connect™ Mobile application (version 1.7.5) on one of our latest Android-powered handsets--the Motorola RAZR (XT910)--we encountered a couple of issues that we thought you should know about. The text on the "whiteboard" will appear distorted when sharing between a PC and the handset, making it difficult to read.
    Steps to reproduce:
    Launch the application client on both a PC and the device
    Login with a username and password on the PC and as a guest on the device
    Select "Collaboration" on the PC client
    Select the "T" on the whiteboard for text
    Select anywhere on the whiteboard and begin typing a note. Notice that when it shows up on the device the font can be difficult to read.
    We hope that this feedback is useful to you in making your application the best it can be on the widest possible range of Android devices. Device specifications for the Motorola RAZR device can be found at http://developer.motorola.com/products/razr-xt910. Also note that you can get early and exclusive access to everything you need to create apps for Motorola's newest devices by joining our App Accelerator Program (AAP).

    I believe it doe run on AIR.
    What do you mean by native extensions? Do you mean objects you can load in the Share pod and have it work in the mobile app?
    I know that you can load PPT(X), FLV, JPG, PNG, and MP3 file and they should display properly in the mobile app. MP4, F4V, and PDF may also work, but I'm not 100% sure on those.
    I do know that SWF content does not currently work in the mobile app.

  • Issues with playback in Adobe Connect 8

    I am a new user to Adobe Connect 8. I just created my first meeting
    yesterday. I was able to hear the playback myself, but when I sent the
    link provided to another e-mail, I was unable to hear the sound from the
    link ( I see all the slides, which run through in 5 second intervals),
    the sound is at maximum level on both the playback and on my computer.
    The second issue I have is that I have received two messages-one e-mail
    "You may be at risk of running out of seats for Adobe Connect. In
    particular, your account (name = QUESTAR III20120321093023) quota for
    Authors has exceeded the threshold of 80% usage on Thursday 16 August
    2012, 08:43 AM. This means you used at least 80% of your 5 available
    seats.  You may want to consider adding more seats to your account".
    Do you have any suggestions for this? I added 4 other colleagues who
    will need to have access to utilize Adobe Connect in the future-should I
    only add them when they need to be the moderator/host?
    I have watched many of the video tutorials, which were helpful but I am
    trying to trouble shoot this in quick fashion as I have been asked to
    turn key train this for staff.

    Thank you for clarifying the Author license usage. Since I am new to this, publishing Content to the Connect server-that is for copyright purposes? Is that a “cloud based” server that allows us access (I am assuming it was part of the purchase). I have moved all 4 people to the Meeting Host group now-thank you for that clarification.
    I have just found out where the link for viewing/listening is: it is located in the recordings section and I am able to click on and listen in the Adobe Presenter
    Here is the link that I used for that: https://questar.adobeconnect.com/_a1134876945/p9lnerpx15j/

  • Unable to Publish Captive 4 into Adobe Connect with Windows 7

    Hello,
    I am using Adobe Captive 4 and have previously been able to publish my Adobe Captivate videos into Adobe Connect.  However, I have now had my PC upgraded to Windows 7 and am now unable to do so. When I attempt to publish into Adobe Connect, I received the following message:
    Adobe Connect requires Flash Player 9.0.0.0 or above.
    I have Flash version 11 installed on my computer so I don't think this is the problem. However, I do notice that the publish option opens in a window that seems to be another program or wizard that is used to publish from Captivate into Adobe Connect; this may be where my problem resides. I had a co-worker on Windows XP try and everything still works fine. It is only with Windows 7 that this problem occurs.
    Any help or direction with this issue would be great.
    Thanks!

    Odd, I just verified that I could publish from CP4 to Connect. Windows 7, Connect 8.2.1, Captivate 4.0.1 Build 1658.
    Have you tried uninstalling and reinstalling Captivate? Maybe it didn't hook into the right version of Flash...

  • Launch Adobe Connect from Application

    I have a custom C#/WPF application that allows a user to interact with a remote traveler.  The application will do the following things:
    Launch Adobe Connect
    Login to  an Adobe Connect account
    Send the remote traveler a link to that  Adobe Connect session
    Interact with the remote user with video/audio via Adobe Connect.
      For steps 1&2 I show an embedded html window with the link to login to the account.  This works fine.  After the login succeeds, Adobe Connect takes over the entire screen, which then hides my custom application.
      Is there a way to do this type of launch without Adobe Connect taking over the screen?  I would like to keep it in a browser window of my choosing so I can organize my user's screen.
      Or - is there a better way to launch Adobe Connect from a custom application?
    Thanks

    I am unable get audio when attending Live Webinars thru adobe connect on my iPad 2 WiFi+3G. For recorded webinars there is no issue. I use Puffin browser in order to play the flash player. Is there a solution?

    Hi gailperdue-
    This sounds like an issue with the website gavirtualschool.org. Does this problem happen when you open the website with other browsers like Safari or Chrome? If so, then you know for sure the problem lies with either Adobe Connect or the website. If that is the case I would recommend you contact the website support or Adobe for assistance.

    TomCT60,
    Is your MacBook using Mac OS X 10.6.8 as indicated in your post? If so you will not be able to fully integrate with iCloud.
    iCloud and Snow Leopard, by Roger Wilmut describes what iCloud options are available for Snow Leopard.
    If you are using Lion, go to iCal>Preferences...>Accounts, and delete/re-add your iCloud CalDAV server.

  • Adobe Connect issues with Windows 7

    Has anyone found a solution to the problems Adobe Connect has with Windows 7?

    Sounds like something is blocking network traffic. I'm not aware of any Windows 7 specific issues. I've used Windows 7 with connect for 2 years with no Windows specific issues.
    I'd call support at 800-945-9120 and see if they can indentify the issue and give you a resolution.

    Thanks, Flex harUI, for the direction in regards to isolating build changes. That aside (still working on it), can you offer any direction in regards to my original question on SDK and AIR compatibility? I'm specifically looking for a version compatibility mapping or anything that definitively states, "Flex SDK x.y.z works with the following versions of AIR". This information is crucial for us in order to more specifically plan our own roadmap built upon these two frameworks as we consider both existing installations of our software and future distributions.
