Pip only works using -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

Description

I have no clue where, to begin with, this error.

Pip does not want to install from pypi.org

pip install --upgrade flask -i http://pypi.org/simple --trusted-host pypi.org 
Looking in indexes: http://pypi.org/simple
ERROR: Could not find a version that satisfies the requirement flask (from versions: none)

Using pip install --upgrade flask -i http://pypi.douban.com/simple --trusted-host pypi.douban.com Works normally however and I am unsure why.

Expected behavior

Using pip install --upgrade flask -i http://pypi.douban.com/simple --trusted-host pypi.douban.com

pip version

21.3.1

Python version

3.10

OS

Windows 10 Pro 20H2

How to Reproduce

This issue happened after installing Tor and Kaspersky and having Kaspersky break a bunch of stuff .
I may have Deleted Tor possibly while in an venv and after this point in time was unable to use pip normally

I have tried reinstalling python multiple times for different versions and have tried disabling ipV6 yet am still encountering the issue.

Below is the output of pip install flask

Output

pip install flask ```

This looks like a network issue on tour side and there's not much we can do about this. Contact your network provider for support instead.

Edit: It's likely your network blocks PyPI access, or at least does not like PyPi's SSL provider. PyPI only supports HTTPS, not HTTP, while Douban's mirror can run on HTTP, which could be the difference. It maybe be useful to discuss this with PyPi admins as well (they can be reached on https://github.com/pypa/warehouse), but this is mostly out of pip's hand without further information, sorry.

For anyone who ends up experiencing this issue however rare I managed to figure out the issue was caused by an TLS /SSL error and corrupted Certificate.
After making the changes suggested by firedog pip works as expected.

Windows + R
control -> Internet Properties / Advanced
Enable only TLS 1.3 and 1.2

I also deleted a few older certificates if the above does not work.
