Artifact upload errors

As requested, here's a job that failed to upload the artifacts. This is an unmodified job and succeeded in the previous pipeline run. The same error has been observed in the same pipeline but for different jobs. These errors happen maybe 1 out of 5 pipeline runs and hitting retry is enough to make it work.

General note: its very common that the first upload fails but with 2 retries it works - most of the time. So there's something odd going on but I don't have any logs to debug this further, sorry.
