I'm trying to connect to a website that uses unofficial CA via https. For some reason it works with curl but not with python requests.
See the example below
Python 3.8.0 (default, Oct 30 2019, 11:47:54)
Type 'copyright', 'credits' or 'license' for more information
IPython 7.9.0 -- An enhanced Interactive Python. Type '?' for help.
In [1]: import requests
In [2]: requests.__version__
Out[2]: '2.22.0'
In [3]: cert = "..."
In [4]: url = "..."
In [5]: !curl --cacert {cert} {url}
{"status":200}
In [6]: requests.get(url,verify=cert)
---------------------------------------------------------------------------
SSLCertVerificationError Traceback (most recent call last)
...
SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get issuer certificate (_ssl.c:1108)
During handling of the above exception, another exception occurred:
MaxRetryError: HTTPSConnectionPool(host='...', port=443): Max retries exceeded with url: ... (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get issuer certificate (_ssl.c:1108)')))
During handling of the above exception, another exception occurred:

What am I doing wrong? Why is it behaving differently?
--EDIT--
curl is using this cert for sure, without it curl fails
In [9]: !curl {url}
curl: (60) server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
