/var/log/docker.log

has this to say:

time="2023-03-06T185919.070815925Z" level=info msg="Download failed, retrying (1/5): read tcp 192.168.5.1559522 >142.251.33.176443: read: connection reset by peer"

We've tracked this to gcr.io (and not pkg.dev) ... using a google affiliate to poke google about the behavior (but we may just ignore the problem and switch from gcr.io to pkg.dev)
