The server can't talk to the master server because you're using an OLD version which had a hard coded address - which the master server now no longer uses. Patch V and above no longer have this drawback.
I have made previous versions "unlockable", and the updated executables are available in this thread:

It's worth saying that I haven't patched Q dedi server though - if you would like I could patch that also. I'd recommend using the patch V or W though, rather than Q.
Quite frankly I'm honestly surprised you've not had trouble finding this out. The fact that patch Q doesn't work is plastered across half the board.
