This is the same error message observed on this platform (in a different test) in #52893.

This error code seems to be ERROR_OPERATION_ABORTED.

Gathering all of these occurrences in one place, since this looks like either a net/http bug or a platform bug exposed by net/http.

I'm looking into this. Still trying to reproduce it.

[bcmills]

There have been a lot of net/http fixes since this issue was filed, and watchflakes will file a new issue should it recur.

@qmuntal, should we close this as obsolete?

Yes, I couldn't repro nor find the culprit.
