I've been wanting to set up a private CS:GO server for weeks now, that would allow me and my friends to play on older versions of maps, like Mirage, Nuke, Cache, etc. I'm using LinuxGSM as a server installer, that gets it up and ready to go within minutes.

I've recently been having an issue that I'm unable to solve, which is that whenever I add a workshop collection to my server, it instantly delists the server from the community server browser, which in turn makes in inaccessible to anyone outside my network.

Anyone know how I can get this fixed? I'm in no rush, but considering that this issue has been pestering me for weeks now, it's getting really annoying that I can't get it to work no matter what I do.
