Sudden "This room is blocked" in Direct Message [SOLVED]

After upgrading server from 5.1.2 to 5.1.4 one of my direct message channels state “This room is blocked” for both users. How to remove this again?


Do you see any outstanding logs in the browser console or server log?

Both users tried block/unblock each other, then it worked again. Dunno what happened, but now it works.
@dudanogueira Thanks for your quick reply :slight_smile:
