So, I have made a bukkit server, successfully (hamachi) and my friends were able to join it on the 30th of April (the day I made it). Everything was going well. However, the next day and today the server would not allow my friends to join. It just says "Can't reach server" They have put in the correct IP with the correct port though still they are unable to join. They are on my hamachi network etc... But having it be working one day, and stop another with out even editing properties has frustrated me. Is anyone sure what maybe preventing them to join and what I can do to fix it? I would be grateful if I get feedback as soon as possible. Thanks! -Kix HD Also, my vanilla server works fine. Which makes me more confused.
