We installed the latest stable release about two weeks ago. Since then, we’ve seen increasing number of screen-sharing sessions result in a lost connection. Usually, turning off screen-sharing results in a recovered connection. For some people, this happens most of the time. For others, it happens rarely.
The audio is unaffected. The screen-sharing video stream sometimes starts for a few seconds, but sometimes will not start at all. A few days ago, one of my coworkers and I could reliably share screens with each other, but the next day we could not.
In some cases, Person A will share their screen in a room with Person B and Person C. Person B may be able to see the video stream while Person C sees Person A as having a Lost connection. In other cases, neither Person C nor Person B can see the screen share video stream.
We are hosting two videobridge servers and one prosody/jicofo/etc server on AWS. The problem seems to be more frequent when there’s a mix of UDP and TCP in one video conference.
What evidence should we be looking at? What settings should we experiment with? What kinds of situations might trigger this behavior?
