I'm trying to install Django on a windows 10 .

Whatever I try to install with pip on cmd, I get those errors

Collecting django

I've tried a lot of things from other questions but none is working. 
pip install --upgrade pip --trusted-host pypi.org --trusted-host files.pythonhosted.org
pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org django
                your firewall is not allowing pip to connect to internet, so allow pip from the windows firewall and it will work

                make sure that you have strong internet connection and allow firewall to connect to pip refer this github.com/pypa/pip/issues/6152

                @Exprator The internet connection isn't a problem so it's probably the company's firewall and I don't think I can allow it myself. Is there another way to install django?

                Doing a trace route might shed some light on where it is being block. From cmd, try tracert pypi.python.org. If you see an address with * displayed, that means it can't reach that hop point.

                @FlipperPA I have indeed * displayed so I guess it can't reach ....This is probably because of the company's firewall and I tried some commands with proxy but nothing seems to works

Setting my proxy correctly fixed this for me as well. Problem was that I used the https protocol for my HTTPS_PROXY and https_proxy environment variable.
HTTPS_PROXY=http://username:password@proxy.example.com:8080"
https_proxy=http://username:password@proxy.example.com:8080"
Do NOT use:
HTTPS_PROXY=https://username:password@proxy.example.com:8080"
https_proxy=https://username:password@proxy.example.com:8080"
                Working. Just also created an environmental variable with the proxy I am using. No need to not upgrade to pip to 20.3.1.

My pip was working fine (Win7, python 3.8.6) until I upgraded pip from version 20.2.1 to 20.3.1, after which I also got the SSL: WRONG_VERSION_NUMBER error.  This is reproducible, I uninstalled and reinstalled several times to confirm.
Solution (well, workaround): don't upgrade pip to 20.3.1.
Note: pip 20.3.1 works fine in my Win10/python 3.9.1 environment.
                I found by trial and error that 20.2.4 was the highest version that works for me with python 3.7.9

                I also ran into this issue with a fresh install of Python 3.9.1 on Win10 and upgrade to pip 21.0.1. Solution was to reinstall Python and stay with pip on version 20.2.3. We have a SSL Interception Proxy and i tried to set global.cert which seems not to be used by pip 21.0.1. I filed an issue: github.com/pypa/pip/issues/9614

I asked a collegue who automatically knew what to do. I just had to set the proxy variables:
"set https_proxy=http://username:password@proxy.example.com:8080"
 "set http_proxy=http://username:password@proxy.example.com:8080"
and it works
                I still have this error :  " Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x0378E390>, 'Connection to 192.168.0.254 timed out. (connect timeout=15)')': /simple/django/"

                This command works fine pip install <package> --trusted-host pypi.org --trusted-host files.pythonhosted.org --proxy="http://<username>:<password>@<IP>:<port>"

In case anyone still having this issue, try finding and removing OpenSSL (OS level installation), if its installed in your system.
In my case, I installed openssl on windows 10 (for some other development tasks) long time ago and forgot about it, which was the main culprit. I uninstalled it and it solved the issue
