My server is showing "offline", but it is online. Why?

There are two possible reasons why we might show an "online" server as "offline". 

The first occurs if you have an RCON subscription with us but have changed your RCON credentials. To make sure that we have the most up-to-date RCON credentials, please see the following article on how to update that information:

The second reason occurs when your server does not respond to our queries. This can happen for a variety of reasons, but they all boil down to a bad route or firewall blocking our traffic from reaching your server.
