I've recieved a couple of reports on my server, from players that has been playing on our servers for a long time and they all report the same, that their TC randomly deauthorizes them even if they are not breaking the limit which is currently set to 4 which should allow 4 players to have access to the TC.

I do have the plugin AutomaticAuthorization but I am not sure which one is behind this.

Edit: If you have the same problem, this is caused by the plugin AutomaticAuthorization and there is a new update for it which will solve this issue.
