FYI, This is how I figured out and fixed the issue on my debian system.
-Run nmap to figure out what ssl version is being used by the server
nmap -p443 -sV --script ssl-enum-ciphers 10.10.10.7
output says TLSv1.0

test 10.10.10.7 using example in this comment (gets expected error)
https://github.com/requests/requests/issues/606#issuecomment-8036266

test with openssl binary (gets expected error)
openssl s_client -connect 10.10.10.7:443

fix by editing this value-->MinProtocol = TLSv1.0
in this file--> /etc/ssl/openssl.cnf

rerun tests without error.
Note the outdated server I am connecting to is internal, non-production, not connected to the internet.
