Hi I'm new to the whole private server thing, in fact this is my first go at it.
So yesterday I followed Judas' guide to make the server and client, however I kept getting the 5011 and 30 error. After hours of trying to sort it out I saw your post so I decided to start from scratch following your steps.
However, I am getting the "Failed to Authenticate" and "Rejected from Server" messages, this time without the 5011 and 30 numbers at the end.
Please help me.
P.s. Thanks for the client
