The launcher is misbehaving. Its telling me all servers are offline even though I know they are not. When I choose singularity it flips over to online. So do TQ when I check the server list (even tells me 30+ logged in). When I switch back to TQ it flips back to offline.
You likely have already tried but in case you did not:
Restart launcher/computer? Or try to reset the launcher to default. (To be found in the " Settings", bottom left of the launcher window.)
Go to your launcher, top right drop down menu, Settings, set version type to “release” yours might be set on development which was my issue.
