Ok so i wanted to start a server so first i made it port fowarding it, and it worked not that well, because sometimes my friends would get disconnected 10 seconds after joining, but only to one of the two (randomly selected). Now my router changed and it wont let me port foward idk why, so i decided to use hamachi, and i have the same error but worse, they can join, and it works fine, but then like 20 seconds later the 2 disconnect at the same time, and i tried almost everything and i don't know what to do, help please.
