Cannot get Bridge to work after restart of Matrix and the Bridge - "You are not invited to this room." / "M_USER_IN_USE"

[blackandred]

Hello,

My issue looks similar to #37 but I don't see there a working resolution for me. I'm actually frustrated getting this to work, as my whole infrastructure monitoring relies on reporting to Matrix.

2021-08-02 21:27:40.570.000	 INFO 	[webhook-srv]  	  	Matrix bridge running on 0.0.0.0:9001

Later I reactivated the "webhook" account and got a little bit different message:

Do you have any clue?
Thanks! :)
