@xhatspy Sorry for not responding in time, if the problem with CustomServer was not registering users we would have learned quickly about this problem through mass complaints, maybe there is some problem on your side, I wrote you a private message with instructions on what to do.
Hello, since a few days there are issues sometimes and now its not working since hours.
I'm running my setup since months like that and now there is always the "Query limit reached" message, even when the server is not running anymore and after a longer waiting period than 3 minutes.
Errorcode: {"valid":false,"message":"Query limit reached","trylater":true}
