Weird Network Issues?

[SL666]

Hi There,

Pretty new to Bambuddy (but not new to Bambu/3D printing/docker), having a couple of strange issues - hoping they can be easily solved.

BB v0.2.4 (with HASS & Fail detection working)
Spoolman Version 0.23.1 (usage tracking works)
X1C (Lan only mode)
Bambu Studio 2.6.1.53

Trying to send a print from BS via - slice - print plate I get this error.

Searching for it - doesn't really give me much information - I have printed directly since this has been set up, but lately i've had to export the sliced gcode and upload into BB and print from there - which does work without issue.

The other is that if I open the camera view of the printer, it will freeze after a few seconds, pressing the refresh button does re-connect and show another few seconds, same behaviour as when it times out and re-connects on its own.

Not sure if I'm using things wrongly etc or ? no errors sticking out in the docker logs.

Cheers Steve.

Update - The camera stream doesn't hang, if there isn't a print going on (watching the stream, turning the light on & off etc seems fine)

edit -

further testing and logwatching - the hangs are happening when the fault detection fires -

Turning off AI failure detection - the camera stream functions normally.
