Cannot install any package with pip 21.0.1 SSLEOFError

Question

I'm using python 3.7 with pip 21.0.1 on Ubuntu1604. I can't install any python package with the error

yc_qian@NiBaBa:~$ pip install pyopenssl

I found the similar issue on github but had no idea how to fix it. I also tried to downgrade pip, but the command also use pip, so it bumped into the same error...

How can I solve this?

I've receive a similar error when running Fiddler on my machine. If you are running it try turning it of. — Felix Eklöf, Mar 09 '21 at 09:57
@FelixEklöf No fiddler, I did run a VPN, but it made no difference if I turn it off and try install again.. — null, Mar 09 '21 at 10:02
