Adobe uses a proprietary protocol for streaming audio over the internet; Real Time Messaging protocol (RTMP).

RTMP will initially try number of different ports across your firewall to provide you with access to the live stream. These ports therefore need to be RTMP enabled.


If all of these ports deny access, Adobe will, as a last resort, use a different protocol; HTTP tunneling. this process can take 1-3 minutes.


Possible causes of overall failure:

    • 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 http://kb2.adobe.com/cps/164/tn_16499.html

  • 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.

Still experiencing difficulties with the stream? We recommend that you contact your network providers IT support for further investigation.



You can check again by restarting the tests.
