Solution 2

As I understand, in new urllib3 the main schema of proxy was changed… can read here.
This settings help for me (for urllib3=1.26.4).

An old

proxy={
    'http':'8.88.888.8:8888',
    'https':'8.88.888.8:8888'
    }

The new

proxy={
    'https': 'https://8.88.888.8:8888',
    'http': 'http://8.88.888.8:8888',
    } 

UPDATED

I have met this issue again for requests 2.26.0, but in this time it works with an old schema…

proxy={
    'http':'8.88.888.8:8888',
    'https':'8.88.888.8:8888'
    }

I have solved the problem. It is a bug with urllib3.

You can use pip install urllib3==1.25.8

Downgrading urllib3 has solved it for me too.
Though I had to reset the proxy env var:
https_proxy="http://127.0.0.1:<PROXY_PORT>" pip install urllib3==1.25.11

Without that, I was getting the following error and it couldn’t downgrade urllib3 (see SSLError installing with pip).

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1091)'))': /simple/pip/
