What should I check first if no servers show?
Restart after any update, clear search filters, compare region, and make sure Steam is online before changing anything else.
Why can my friend see a room that I cannot?
Compare your region, tag filters, spelling, version, and search state against the player who can see it.
Why is the server list empty?
Clear optional filters, confirm region, restart after updates, make sure Steam is online, and run one clean search before changing room settings.
Why is my private server or private room not showing?
Most private room problems come from mismatched region, tag, room name, password, open slots, lobby state, or version. Have the host wait in the lobby and resend one fresh room card.
What should I do if matchmaking or online play is not working?
Separate the problem first: server list, private room, failed join, sign-in, input, install, or platform state. Use the matching table instead of trying every fix at once.
When should the host rebuild the room?
Rebuild after everyone has restarted after updates, compared filters and room details, confirmed open slots, and tried one clean search.
What if I see an invalid or missing authentication token message?
Restart Steam and the game, avoid alt-tabbing during startup, and stop at official support if sign-in still fails.
How do I know this is not a lobby problem?
If the problem mentions account access, purchase state, platform sign-in, token status, or the UI cannot be clicked before search, handle that first.
Should I reinstall the game?
Only consider reinstalling after safe checks fail: restart after updates, rebuild the room, compare filters, and confirm the issue is not account or platform related.
Is this the same as joining friends?
Not exactly. Friend setup is about matching room details. This page is for broader server-list, failed-join, patch, and sign-in symptoms.
