This issue appears to be related to the following upstream Github issue. When uploading (either via POST or via PUT) big files, Python errors out immediately.

The two reproducers (one for requests, one for http.client) outlined in the upstream issue have been tested, both on RHEL 8 and 9, and using Python 3.9 and Python 3.11. Python 3.11 is affected, both using requests as well as http.client.

RHEL 8, Python 3.9, requests (python3-requests-2.20.0-2.1.el8_1.noarch), unaffected:
