A 502 Bad Gateway error usually indicates that Home Assistant isn't responding to requests from `cloudflared`. This could be due to Home Assistant being overloaded, experiencing errors, or being unreachable from the tunnel. Check Home Assistant's logs for errors, ensure sufficient system resources are available, and verify the tunnel configuration is correct. Also, temporarily disable any Home Assistant integrations to see if one is causing the issue.
