[FIXED] SSL error unsafe legacy renegotiation disabled

Issue

I am running a Python code where I have to get some data from HTTPSConnectionPool(host='ssd.jpl.nasa.gov', port=443). But every time I try to run the code I get the following error. I am on MAC OS 12.1

raise SSLError(e, request=request)
requests.exceptions.SSLError: HTTPSConnectionPool(host='ssd.jpl.nasa.gov', port=443): Max retries exceeded with url: /api/horizons.api?format=text&EPHEM_TYPE=OBSERVER&QUANTITIES_[...]_ (Caused by SSLError(SSLError(1, '[SSL: UNSAFE_LEGACY_RENEGOTIATION_DISABLED] unsafe legacy renegotiation disabled (_ssl.c:997)')))

I really don't know how to bypass this issue.. thank you for the help!

Solution

This error comes up when using OpenSSL 3 to connect to a server which does not support it. The solution is to downgrade the cryptography package in python:

run pip install cryptography==36.0.2 in the used enviroment.

EDIT: Refer to Hally Mallon and ahmkara's answer for a fix without downgrading cryptography
