Join Server failed on Invalid Permission: 0x28

<03:58:50> Trying to connect to server on x.x.x.x
<03:58:51> insufficient client permissions (failed on Invalid permission: 0x28)

User is unable to connect to one specific server. There is only one forum post on earth somewhere else, but it was didn’t quite match the issue it seems.

Is this a client or server side issue?

Server version? Client version?


I’ll double check the other servers version. But he’s using the same and latest client version as everyone else on my server and none of them have this error and can connect fine.

I also noticed this only happens when connecting with a bookmark. Doing a manually connection with the connection menu allows the connection to work.
Client logs say nothing.
