Fabiano's Source: Socket Server Error?

When creating my Fabiano's Server, I changed the ip correctly and currently using Hamachi. When sending to friends, they can register and login fine but when they try to connect, aka press "Play", they can't load in and get Server Socket Error: #2031.

Don't quote me on this but I think it's to do with your defined IP addresses in Parameters.as in the client.

nah, the ip in the client is the server sided ip basically, then the ip in the server is the wserver sided I guess, id what other way to put it, but he probably changed the client IP because as he said he can connect to home page and register etc. but he cannot load into worlds (nexus) meaning he didnt change server.cfg ip most likely
