Hey @Sean Leakehe, I have never seen this before. Is the Prefect Cloud or Server?

or you can try bumping up the read timeout setting?

Seems like it could be a load thing? Are you starting up a lot of containers when you see this error?
s

12/30/2021, 4:54 PMI think there could be as many as 4 containers that get spun up at the same time.

I think it’s hard to guess the impact of 4 containers without knowing the resources of the machine, but the comments of the StackOverflow link I sent seem to suggest bumping up resources may help (in addition to the timeout settings)?
