Hi. Unfortunately same for me.

pip version

• 21.2.4

Python version

• python 3.10

I use python at work at corporate machine. So I stand behind proxy NTLM. Therefore I have edited global config for pip to set proxy. Before use of CNTLM I got different eror but now I am stuck at this point as well. Could be related to this issue. But I am not sure at all.

pip config list

http.proxy=http://localhost:3128
https.proxy=https://localhost:3128

You probably need to add the pip config "trusted_host" and set it to "localhost".

The description of your setup means you probably can't verify from pips side the certificate is correct, this needs to be done by your proxy. But your NTLM proxy should be doing that for you, so you can "trust" it.

SSL issues are usually the result of enterprise firewalls, proxy misconfiguration or other environment issues (ie. it's not pip's fault). Given the lack of any follow up in ~2.5 years, this issue can safely be closed.

If anyone lands on this issue from a web search: you will probably be better served by reaching out to peers or help forums, such as Python Discuss help category, /r/learnpython on reddit, Python Discord's #python-help channel, #python on Libera.chat (IRC), python-list or python-tutor mailing lists, or StackOverflow.
