<Pwa> Or not. After spending wayyyyyy too long figuring out how systemd works (sorry I have very little experience with linux), I disabled the videobridge service so it wouldn't start on boot. I made a timer start on boot instead that would start the videobridge service after 30 seconds. The videobridge now successfully binds the port the first time around. So there is clearly a time component to this problem, but I didn't figure out what exactly it is that wasn't ready when the videobridge service starts. This doesn't seem to be a problem for anyone else, though, since I have seen nothing on the forums about this, and the Jitsi Yuno app is considered to be working; so something about my environment seems to be the cause. My environment is pretty sterile overall though, I only have the Etherpads app and the "Cockpit" one (web monitoring app)...
Well, either way I'll settle for this now, I imagine I'll have to redo this manipulation every time I update the Jitsi app and that's a bit annoying but realistically I'm not going to be updating it that often. Thank you very much for your help otm33
