Adobe Flash Media Server port connectivity survey

If you do not see the movie on this page, please check that you have Adobe Flash Player installed correctly.

The test above determines which ports the Adobe Flash Player is able to connect through to the Flash Media Server located at Adobe.com. All users should pass this port test because HTTP Tunneling technology has been implemented on the server. If you have success on any of the tests, that means you will be able to successfully connect to and view Flash Media Server content from the computer network you are connected to.

Note: If your results are both failures and successes you still pass the overall test. Success on any single test is the indicator.

If all the tests fail, then you have failed the overall test. This means you will not be able to successfully connect to and view Flash Media Server content from the computer network you are on.

Possible causes of overall failure:

Adobe Flash Player is out of date. Upgrade to Flash Player 6,0,65,0 or higher.
You may be behind a "stateful inspection" firewall. These firewalls will drop socket connections if they detect non-HTTP traffic such as the Real-Time Messaging Protocol (RTMP) traffic used by the Flash Media Server. For more information on firewalls see Ports, Firewalls, and Adobe Flash Media Server (TechNote tn_16499).
You are using a proxy server to connect to the Internet. Most proxy servers only negotiate HTTP traffic. For this reason, attempts to connect to the Adobe Flash Media Server using RTMP through a proxy server fail.

Adobe is working to resolve this issue and is interested in any data you can provide regarding your proxy server, firewall, and browser. If the test movie above fails on certain ports, an email window will be opened containing several questions. Answering these questions will help us better test our upcoming solutions. You may also provide contact information for yourself or someone in your IT department if you would like to participate in upcoming solutions we are testing.
