This is a really hard thing to fix. Okay so I host my Bukkit Server on Hamachi XD. Also the other day I was on my Server and then left the pc and left the RUN.BAT running for quite a while, but when I came back my pc had locked it self. So the RUN.BAT had stopped, therefore my Server had stopped, but it stopped without typing /stop in the command, which is bad. Then again yesterday I installed ccleaner and just did a clean up. I also unistall mcafee so do I need to let hamachi through to my pc again. When people try to log on it says connection timed out. If you solve this, thank you so much because I bet I am the first with this problem... Thanks once again for reading all of this, but a big thanks if you can fix this massive problem.
If you uninstalled mcafee its possible it had a firewall that it removed and replaced with windows firewall afterwards. Check with windows firewall settings would be my first idea. Can you connect to it locally ? As in, on the computer running the server?
Yeah I can get on my Server, also I checked windows firewall and ticked both boxes about Hamachi, but I don't know if they're the right one.
