If you are in LAN-only mode, select Developer Mode on the printer.

I'm not in LAN-only mode - it is toggled off I didn't know there was a developer mode, and would like to turn it on if possible.

Sorry, I missed that you are using Studio 1.10.1.50. With the new "authorization" required by X1C firmware 1.08.05, you need to use Studio 1.10.2 or higher to establish a connection via cloud.

Developer mode bypasses authorization, but requires LAN-only mode and cannot be used with Bambu cloud services.
