Help with server please?

[Erikai]

I'm extremely new to private servers, and I managed to get my files together (from aion-java) and make the database with Navicat.

I can log into my server nicely, but when I go to select the server it says that it is "Down".

Where do I go to change this, and would this error have anything to do with it?

I had the same error but I fixed it by changing the port... (9014 - 2106)..... Idk how exactly but I got it working. D
