FOSS gamedev and creative worlds

So there is 1 server and it is the only server that does this. I can get on once but then if I leave or it crashes and then later I want to get back on, it won't work just gets stuck on the connecting to server screen. Nobody else seems to have a problem on that server. I have also tried deleting my debug and my media cache. Nothing seems to work. Please try to help me understand the issue and also I have tried restarting my computer and the client. Thank you!!\

What server is that?
I had once a problem in a server, crashed when i logd in, someway my user name data were corrupt in the server, perhaps for a faulty mod. Try to login with another user name or just add a letter to yours to change it, if the problem keeps going maybe is your client fault, maybe you have dev client and server is stable or vice-versa.

It is RRH-Economy and thank you for trying to help but I have tried on other versions of minetest. I can't really change my name any because I administrate on that server. I can log into other servers just fine. I don't know what I will do, hopefully I will figure it out eventually.
