Printer

Bambu Lab P2S

How to reproduce

Connect to P2S printer via cloud (not LAN-only mode)
Sign in with Bambu account (authentication works)
Try to view camera feed - get "connection failed"
Try to send a print job - get error -3120

Actual results

Expected results

I can see the printer status and temps just fine, but when I try to use the camera or send any files, I get:

Error code: -3120
Error desc: Check the current status of the bambu server
Extra info: [http code): 403
[reason]: internal blocking

The camera just says "connection failed" and won't show anything.
