Multiplayer server not working today?

[Onitsuka]

My tekkit mulitplayer server was working perfectly fine yesterday, and now today it's not working. It loads and after it says "done", no one can login my server. My server is port-forwarded and like i said it was working yesterday. There is no errors i can see. My server is up and when me or one of my friends click multiplayer is just says "can't connect to server". What's going on here? I'm using java jre version 7 and im running on a netbook. I'm using the latest recommended build and latest tekkit. I didn't put a log because there is no error and everything looks PERFECTLY fine.

Could it be a dynamic IP?

By "latest" tekkit do you mean 3.0? If you are then the minecraft screen will say it is running on MC version 1.2.5..

If you are all using that then the reason you can't connect is you are trying to connect a 1.2.5 client to a 1.1 server. There are no 1.2.5 server files at the moment so you need to use the correct client files.

When you fire up the technic launcher, with tekkit selected click on options. The make sure you have recommended build selected, NOT development build.

If it's not that then no idea. You've given absolutely no information to go on .
