The issue you are facing:
I have tested standalone version of nextcloud and it’s AIO version in docker and in both versions I have encountered a p2p connection problem while using configured hbp server. If there is no hbp server in talk administation settings - I see that there is p2p connection between 2 users of talk. If hbp is enabled then only turn connection is possible.
Does nextcloud talk have such an issue or it is something I didn’t configure correctly?
