The reason this isn't added is because your internet might be not good enough or server might have a firewall rule to skip some requests and process only like one in five requests, and that way omp launcher thinks server is offline, which it isn't. There's no need for this PR

then, can't we handle it in a way that it shows 0 ping? because when the server is offline, it almost looks like its online. IMO that is kinda stupid

can't we just remove the (Offline) tag and keep the gray color on offline servers?

I'll think of a way to o this properly , but only when you launch the app at first
detecting offline servers after they become offline while launcher is open is not neither needed nor necessary, just like how samp launcher works
