P1S Camera feed only works in LAN Mode

Hello everybody,

i got a problem with my P1S. Got it up and running about 2 months now.

Since the start I could not get the camera to work. I only get a picture in LAN Only mode.

Since I want to use the Bambu Handy App to monitore my prints on the go staying in that mode is no option.

Bambu Support is kind of useless.

I only get a error message as you can see in the picture. Same error on Bambu Handy.

Display shows me that HMS Error Code.

I already tried to change settings in my Router as also connect to different mobile hotspots, tried different firmwares.

Also get the same error when I connect to the printer via Orca Slicer.

At the current state I do not know what else to try. Maybe somebody had the same error or has an idea what else I could try.

Thanks for your help and suggestions in advance.
