UM3 stuck after manual pause

[kfsone 5]

11 hours into a print, a piece of the skirt separated from the build pate and got onto the top surface. I selected Pause so I could remove the debris, but it's not accepting Resume from the front button or from cura connect.

It's keeping the print bed at 85c but the print head has now cooled to ambient, and it continues to just sit there 😞

- Printing single Extruder with nGen, bed 85, ext 240,

 

Only thing different about this and previous pauses is that I had manually adjusted the extruder 1 temperature -1 degrees.

Hour later: still no resume =(
