Motivation

This error happens occasionally:

ERROR: (gcloud.compute.ssh) There was a problem refreshing your current auth tokens: ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))

I reopened #5069, I'll let you decide which ticket to use.

I'm not sure if reopening tickets is a thing in our workflow

I reopened #5069, I'll let you decide which ticket to use.

I think the errors are different?
(They might have the same cause, I guess we'll find out when we fix one of them.)

It works for me, but that's really a question for Pili.

On a launch step in PR #5521:

From PR #5508:

But this was an interim logging step that didn't run too long, so the test still passed.
