I used this master server for my L4D2 server a few years ago, I decided to play L4D2 again with some friends so I set up another server.
However, I can't add my server. It gives me this:
[Wed Apr 9 20:38:09 2014]: Verifying 22.214.171.124:27015 (126.96.36.199:27015)
[Wed Apr 9 20:38:09 2014]: Got KEY (l4d) from 188.8.131.52:27015
[Wed Apr 9 20:38:09 2014]: Server reply: 9This server is using a newer version ( 2135 ) than your client ( 0 ).
[Wed Apr 9 20:38:09 2014]: FAIL. Server denied me.
I also tried doing this yesterday and the day before.
To me it looks like it's working, but of course setti got denied because it's giving the "wrong" game version.
Is there anything I can do to fix this?
