I was playing with one of my friends a few months ago on an adventure map, everything was working fine we were connected.
Though I had to unexpectedly run off for a bit, when I got back and tried to rejoin I couldn't connect.. We tried EVERYTHING.
Unfortunately we can't run an actual server and not just Hamachi LAN.
Can someone provide an explanation or a tutorial or something? I want to play on a map again with one of my friends but I can't get anything to work for like 2 or more hours.
