I need serious help! My server Direct Connect is not working or anything!

I have a total of 5 servers. I only have 2 up right now, but my problem is that servers 1 & 2 are the same! They do have different license keys and different ports. They worked before but now Only server 2 is working with Direct connect and server 1 is not working at all but I seem to be able to use local host to enter it. I need someone experienced enough to be able to fix this problem. And yes, all the servers are exactly the same!

What error message is seen when attempting to connect to server one? Or does it simply say the server cannot be found?

Nevermind my local IP changed, I just port-forwarded to the new IP
