You are failing to connect to the host lobby.
This is either because you or the host has software or configurations blocking the P2P connection. This is most commonly caused by ad blockers, privacy/tracker blockers, or firewalls.
How to fix:
- Host/You have slow internet or great distance between you. May take longer to connect.
- Disable your ad blocker (e.g. uBlock Origin, Brave Shields) for this site.
- Disable tracker blockers or privacy-enhancing extensions.
- Try opening the lobby in a different browser.
- Make sure the host is still online and the lobby code is correct.
