2. Version of python you are running: 3.9

• A redacted version of your .pypirc file (REMOVE ALL USERNAMES & PASSWORDS BEFORE UPLOADING)

PKG-INFO: https://gist.github.com/shuklak13/0150db1afcbd11e531e3f365b4e3a662
.pypirc: I did not find a .pypirc in my environment or my project.

The Issue

When executing python3 -m twine upload --repository testpypi dist/*, the message Uploading distributions to https://test.pypi.org/legacy/ will display. The terminal then hangs, and does not display any further prompts. I manually killed it after one hour.

Steps to Reproduce

This issue occurs when I run the following commands:

1. python3 setup.py sdist bdist_wheel
2. python3 -m twine upload --repository testpypi dist/*
