Something is wrong with https://www.gametracker.com/server_info/145.239.237.104:27305/

Correct status https://imgur.com/a/pYDdn

The same in panel - https://imgur.com/a/sQ7Yr

I tried to add it on GT for test but i see error - https://imgur.com/a/qLNlD

As You can see there are few more servers on that IP so it should work properly - https://www.gametracker.com/search/?query=145.239.237.104

Moved: Not a Gametracker bug.

As you can see, many other servers are being scanned correctly.

The issue therefore must be with your server, firewall, server or game configuration.

Sometimes empty servers do not return scan results. If players have recently joined then it may take a while to show results.
