I see these console errors and the participant connection is seen as Lost as soon as the 2nd participant joins the meeting. You can recreate the issue by joining this meeting once through a normal browser and secondly through incognito mode to join as a 2nd participant. As soon as you join as a 2nd participant the connection is lost and you cannot conduct the video call anymore.
Using the latest version of the entire Jitsi self-hosted stack.
