So me and my brother have been trying to create a server for a while now on the latest version but it never seems to work, we have tried using hamachi but that never seems to work, we have our computers in the same room and even when we just try using each others ip address's but it never works, i remember getting it to work once but i cant remember how. I launch the server and hamachi and then he tries to connect to me with my hamachi or normal ip but it doesnt work, it just says "failed to connect to server" and says it cant connect, neither of us can connect to each other, or our own servers and we would just like any advice or help. Any help on how to launch a server for just the two of us to play on would be greatly appreciated. Thank you in advance.
