It seems to be quite a common issue, I didn't see a fix for it.

I've got a gameservers.com hosted BO1 server that i'm trying to add without any success. I figured these guys have whitelisted all the gametracker ip's seeing as they haven't given me access to that higher level server admin stuff I can't really check.

173.199.81.25:3074 - Here is the IP i'm trying to add.

If anyone could point me in the right direction for a fix/guide or even get this issue resolved for me, it would be much appreciated.

Thanks

Edit: This has managed to resolve itself, I don't think anyone did anything, the server is fairly new - I think that possibly had something to do with it? For those who may be reading this and have the same issue - just wait awhile and see if that works.
