I´m experencing issues when a particular buddy joins a stream. The person is not connected via VPN, and everytime he connects to the stream it immediately stops for all watchers, when he leaves it starts running again like a charm. The problem started 3 days ago (06/12/2026) out of sudden, before everything was working fine on his side. No changes on serverconfig (I know peer2peer, but for the sake of completeness mentioned) or clientconfig were performed.
