Hello. My server showed dead, when it was cs:go, sometimes online, most of the times dead. There was a little of work around of this issue, switching it to 1.6 and back to GO, but now can't switch it back to GO, and it shows online as CS:1.6, even tho that IP address doesn't exist on 1.6.

There is no firewall, server is online, IPs are alright, did a traceroute, the port is the regular port, 27015, so I really don't know what the problem is. Thanks

You don't say why you cannot change the game type or what happens when you try.

after 7 hours it finally fixed itself, when is going to happen again, I will also make a screenshot. I cannot change it back because gt cannot scan my server, being a cs:go server, only as cs:1.6. For now, by some miracle, it shows online, and could change it back to cs:go.

Shouldn't your question be : Why is this server read as CS:1.6, Alive, when in fact is CS:GO server?

It's not an actual miracle.
It is a script that runs (I believe) daily/nightly to correct server game types where it is possible to determine the type.

Well, something like this happen.
