Can't connect to the server

This is my first time installing Vassal and I can’t connect to the server. I don’t think the server is down though because I used the link on the main page and there are plenty of games currently on it.
Could someone give me any clues to why? I have turned off my fire wall too, to no avail if that’s a question.

Thanks in advance.

I finally figured out the problem. I screwed up a router setting is all.
