It's working fine... for me. No one else can log onto it. I've tried all possible URLs.
As the creator, I use a different URL from everyone else. The server works fine for me, however no one else can log in. It's non-dedicated, and whenever anyone else tries to log-in it tells them "Connection failed. The server might be down!" or something.
Please help me, I really have no clue what to do...
If you want to host it for me, feel free! :biggrin.gif:
Well, sounds like you're behind a router without ports forwarded. How to forward ports depends on your hardware, so go to http://www.portforward.com, find your router model and follow the guide, the port you want to forward is by default 25565.
If that doesn't work, check out this thread, which contains some more ideas. And if they don't work, visit the minecraft IRC channel linked to in the header. And if you solve the problem, post the solution in the thread I linked to earlier.
