Hi everyone and thanks in advance for any help you can give me. Launching 'pipreqs . ' I get the following error:

I have already tried searching the Internet and I can say with certainty that I do not use proxies, I can connect to the pypi.python.org and pypi.org sites from both browser and shell. I added the crt of the pypi.python.org site to my pem file. I don't know what to do anymore.

Tnx

Hi @momift u get this on company network? Same here, I believe this is to the common mitm attacks companies like to do with breaking the SSL encryption and signing with a company certificate afterwards...

Using pip I can set trusted-host in ~/.pip/pip.conf or use --trusted-host argument. Can we add same option to the pipreqs?
