Hi Adam,
thanks for your reply and the detailed desciption!
This is what I get out of it:
What I would like to add:
The mentioned entry in the network is the last one I get, when I enter the chatroom (result: aborted).
It does not appear in the moment I get the "Not Subscribed" error; also I was not able to reproduce the error 100%-ly, it also seems to be different, from one chatroom to another.
All in all it's a very strange behaviour, maybe you can shine some light on this :)
Thanks & kind regards
Stefan
