Reverse Websocket Proxy malfunction #446
Description
The reverse websocket proxy running on the OpenFire server, that intermediates between the participant browsers Jitsi Webmeeting instances and the Jitsi Video Bridge, tend to drop backend connections in use. In addition, the corresponding frontend connection isn't terminated. For this reason, the Webmeeting client don't get aware of this and will not use it's recover mechanisms. In the case of a broken backend connection, the client will send into the void and don't receive messages anymore.
The affected communication channel is used between all the participant clients and the bridge to interchange information about available bandwith and used video resolution. Without this, the client will drop down to lowest video quality or stop the video transmissions at all.
