For a while now, I have not been able to run L4D2 on OpenGamePanel, till they recently had a fix in reaction to a Valve change in the query protocol ref.

I noticed that Gametracker can not see the server running as well as Sourcebans++
Does anyone have a patch to fix Sourcebans++ so that it can query the server?
