Strange failure querying hotends while in progress #9

Open astrobokonon opened 1 year ago

Not sure if this is just a "busy" sort of signal from the ultimaker API or something, but I am seeing more failures along these lines:

Looking at the lines in question

I can just wrap them in a try...except block and see what comes out after that. Has happened once a day for the last 2-3 days now.

A better fix it to adjust the api helper file to account for this sort of thing, but I'm curious if more stuff downstream will fail so I'm going to try this.
