With both of my games I have 5 players - and when we have logged in, invariably everyone is missing 1 or 2 peoples audio/video. It is not always the same people, nor the same people after a refresh (log in, person 2 is missing person 5, on refresh they now miss person 3, and persons 1 and 4 can’t see them, etc). Everyone also from login and during refreshes, 1 or more people on any given round also gets a “Lost connection to the signalling server”. We try refreshing the page, logging completely out and back in, people clearing their caches/cookies, and even so far as me shutting down and restarting the server. And most of the time after 10 or 20 minutes of refreshes, everybody finally gets everybody else, and it’s stable for the rest of the session.
This evening, after 45 minutes of never being able to get everyone to see everyone, we gave up, and fired up a different video chat program. We prefer the smoothness and clarity of the a/v in Foundry, but this was maddening. I’ve confirmed that neither I nor anyone was running any script blockers or extreme security settings on their browsers (a mix of chrome, chromium, and firefox browsers).
