Since February, I pretty much have the similiar issue like mentioned in this post:
My jobs are starting, but they never finish.
The progress bars just stop at 0% (for all 3 possible jobs).
By contrast to the old issue from above, it states “Runner Activity: Not in the last hour.”
Yeah, sorry for being so impatient and crossposting. As this seems to be very specific, I answered in the other thread only. (but can update here, if I find a solution)
