1. Check whether the game just updated
Lobby-list bugs often appear right after a patch when some players have the new build and others do not.

MECCHA CHAMELEON Server Not Showing Fix
Use this page when public rooms, friend lobbies, or the visible server list simply do not show up inside MECCHA CHAMELEON.
Short answer
If the room list is empty, assume a lobby sync or version issue first. Refresh Steam, update the game, and compare with the live status page before reinstalling.
2. Restart the game and Steam
A hard restart refreshes the lobby feed and clears stale room data more often than people expect.
3. Verify game files
Missing or broken files can stop lobby data from rendering even when the backend is alive.
4. Test another network path
If possible, compare Wi-Fi vs wired or disable a VPN. Some local routes interfere with room discovery.
5. Move to the can't-join guide if lobbies return
Once you can see rooms again, any remaining failure is a join-path issue rather than a discovery-path issue.
FAQ
MECCHA CHAMELEON Server Not Showing Fix FAQ
Why is the MECCHA CHAMELEON server list empty?
The most common causes are a fresh patch mismatch, temporary room-list syncing issues, stale Steam login state, or a local network problem.
Is this the same as a full outage?
Not always. If live player count still looks healthy, the game may be online while your lobby list is failing locally.
What should I try after the list reappears but join still fails?
Use the Can’t Join Server page next, because the problem has moved from discovery to matchmaking entry.
