I followed the instructions for the manual installation with some small modifications that I pieced together from different posts. Now everything is working as soon as > 2 users are in the room. When there are exactly two users, they can see the other is present, but do NOT receive the audio or video from the other participant. When the room has 3 participants, everything immediately begins working, and when one leaves, it immediately stops working again.
The JVB logs have warnings like this
JVB 2021-09-06 22:56:12.046 WARNING:  [confId=d53606d5139bb5f3 gid=10782 type=video conf_name=wow@conference.MYDOMAIN] ChannelShim.lambda$setSourceGroups$2#289: Ignoring source group with <2 sources:

And SEVERE errors like this:
JVB 2021-09-06 22:56:32.535 SEVERE:  [confId=d53606d5139bb5f3 epId=b6cb0ad3 gid=10782 stats_id=Helga-JXp conf_name=wow@conference.MYDOMAIN] DataChannelStack.onIncomingDataChannelPacket#81: Could not find data channel for sid 0
I have only seen other posts where things work with 2 users, but not more. Any ideas what could be causing this & how to fix it?
