Can't leave #matrix:matrix.org
i had problem with connecting to this room (endless messages loading) so I first thought I'll send message there and see it that changes anything. Nothing. Then I thought I'll leave room, and join again and see if it works. I couldn't leave because of error 'not a known room'. Same thing on web client, but I can see messages. Can't send them though. So now I can only read this room in web client, but can't do anything else anywhere I tried.
EDIT: I can only read room up to the point when I left, no new messages are appearing.
Error occurs on every client, leading to the timed out.
The room icon as well as the name turns into a blank icon and <account name> and XXXXX others.
