Python client error 'Connection reset by peer'

While installing requests library it skips few of optional security packages ('pyOpenSSL', 'ndg-httpsclient', and 'pyasn1') which are required for the SSL/Https connection. You can fix it by either running this command

pip install "requests[security]"

or

pip install pyopenssl ndg-httpsclient pyasn1

Installing the optional security packages did not work for me, just in case someone as the same error message, check that the url you are trying to use is correct.

For instance if the server expects a connection on a different port, it is possible you find this error.

I tried installing all the optional security packages provided in the answer above. But nothing seemed to work.

One important GOTCHA : Check if your url end-point actively prevents programmatic access.

Take a look at the robots.txt file in the root directory of a website: http://myweburl.com/robots.txt.

If it contains text that looks like this : User-agent: * Disallow: /

This site doesn’t like and want scraping. This gives you the same dreaded error 54, connection reset by the peer.

Here is a snapshot :

I had the same problem, but installing the optional security packages did not work for me too.

I had to downgrade requests version from 2.25.1 to 2.21.0
