Connection reset by peer when trying to upload to PyPI with Twine

[loewenheim]

My Platform

We upload Python artifacts to pypi.org with Twine as part of our release process. In a significant number of cases, the upload fails with a "connection reset by peer" error. The attached log contains one example of such a failure. twine-log.txt

Platform:

• OS: Debian Bullseye
• Twine:

  twine --version
  twine version 3.3.0 (pkginfo: 1.4.2, requests: 2.25.1, setuptools: 52.0.0, requests-toolbelt: 0.9.1, tqdm: 4.57.0)

• Network: This is running in CI on GitHub. The network stats below were created by means of a GitHub action.

@loewenheim Have you been able to reproduce this with a recent release of twine? If possible, please provide a log of the failing process passing --verbose to twine for some more details.

Hi, apologies for the late response. It took us a while to be able to test this with a newer twine version. This is a similar failure with version 4.0.2 on a different repo:
