Connection refused to server

[Lord_Drake]

Title: Connection refused to server

Version: 3.0.3/3.0.4

OS: OS Snow leopard

Java Version: JAVA SE 6

Description of Problem:

When trying to connect to the server, I get the following error message: Failed to connect Connection refused

I also tried connecting with Localhost.

I actually don't know how a correct tekkit server log should look like, but compared to simple minecraft servers, mine doesn't say: Done! at the end, showing that the server is ready to be used, so the problem may be there.

(sorry if there's syntax errors in this message, I still have difficulties with english)

Sorry, everything is okay! I figured out what to do.

The post is 3 weeks old. Give it up. It's a very common issue, and there are threads all over about it. Update to Java 7 correctly, or delete the Nether Ores .jar from your server's mods folder.
