I've had a problem almost like this, i was playing with my sister on a normal server and then we wanted to play tekkit so i set up a tekkit server, we could play fine until the following day, i started up the server and it loaded fine but when i clicked multiplayer i get the message "can't reach server", i can see the server is up on a normal minecraft but cannot connect because its not tekkit (its just minecraft). I believe its just a tekkit bug. If you found a fix i would be very grateful, thanks -Liam429
