Hey.

I have noticed that CS2 servers that are full or close to full appear as offline on gametracker. I believe this is due to the a2s players query timing out after a certain playercount. I do not know the specifics but I do know that I had to drop the playerlist query entirely in my discord bot, other sites that track cs2 servers also do not show the playerlist above a certain playercount (around 50-55).

So, it seems like the A2S player query kinda dies when CS2 servers get crowded. If there are more than, say, 50 players, trackers start to time out. Until Valve sorts out the query load, most sites – and even your bot – will probably keep saying the servers are “offline.”

Looks like GT can time out on high-pop servers, so if you’re running CS2 it helps to properly tune query/ports — this CS2 dedicated server guide breaks it down well: https://blog.cs2.ad/cs2-dedicated-server/
