The host is reachable, but nothing is listening on the configured port. Check the printer service and port.
The Printbuddy host cannot reach the target. Check routing, firewall rules, VLANs, DNS, and printer power state.
Credentials or tokens are missing or invalid. Check Moonraker tokens, PrusaLink credentials, Prusa Connect tokens, or application permissions.
The URL path is wrong for the selected provider. Common examples:
- Using a Fluidd UI URL where a Moonraker API URL is needed.
- Opening
/camera/<id>outside the Home Assistant Ingress base path. - Using a PrusaLink endpoint against a non-PrusaLink printer.
The connection may open but not receive usable status data. Check provider type, serial number casing for Bambu, and status endpoint responses for Moonraker/PrusaLink.
Check Docker volume ownership and PUID/PGID settings.
