Python Ssl.Sslerror: [Ssl: Certificate_Verify_Failed] Certificate Verify Failed (_Ssl.C:748)

Python ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:748)

Finally, I have the solution:

It is possible that win2012 has outdated SSL library. So, the solution is to indicate explicitly that schema is http:

The correct code is:

from geopy.geocoders import Nominatim
from geopy.exc import GeocoderTimedOut

def getLocation(name):
    geolocator = Nominatim(scheme='http')
    try:
        location = geolocator.geocode(name, timeout=5)
        return location
    except GeocoderTimedOut as e:
        print("Error: geocode failed on input %s with message %s" % (e.msg))

I found a solution after 4 hours of effort.

def conn(senseHost, userDirectory, userId, privateKeyPath):
    url = "wss://" + senseHost + ":4747/app"  # valid
    certs = ({"ca_certs": privateKeyPath + "root.pem",
              "certfile": privateKeyPath + "client.pem",
              "keyfile": privateKeyPath + "client_key.pem",
              "cert_reqs":ssl.CERT_REQUIRED,
              "server_side": False
              })
    ssl.match_hostname = lambda cert, hostname: True
    ws = create_connection(url, sslopt=certs,
                                header={'X-Qlik-User: UserDirectory=%s; UserId=%s'% (userDirectory, userId)})

context.load_verify_locations('mail.google.com.crt')

Verify locations are expected to contain trusted CA certificates. The server certificate you've specified is no CA certificate. From the documentation:

Load a set of “certification authority” (CA) certificates used to validate other peers’ certificates ...

requests.exceptions.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)

You need to download the GoDaddy root certificates, available at this site and then pass it in as a parameter to verify, like this:

>>> r = requests.get('https://aucoe.info', verify='/path/to/gd_bundle-g2-g1.crt')
>>> r.status_code
200

If you'll be doing multiple requests, you may want to configure the SSL as part of the session, as highlighted in the documentation.

Python requests SSL error - certificate verify failed

As already pointed out in a comment: the site has a bad SSL implementation as can be seen from the SSLLabs report. The main part of this report regarding your problem is:

This server's certificate chain is incomplete. Grade capped to B.

This means that the server is not sending the full certificate chain as is needed to verify the certificate. This means you need to add the missing certificates yourself when validating. For this you need to include the PEM for the missing chain certificate C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert SHA2 High Assurance Server CA and also for the root CA C=US, O=DigiCert Inc, OU=www.digicert.com, CN=DigiCert High Assurance EV Root CA info a file my_trust_store.pem and then you can call:

requests.get("https://...", verify='my_trust_store.pem')

... but I've tried downloading the site's certificate and pointing to that file using the verify option

This will not work with normal leaf certificates. Since the SSL stack of Python is based on OpenSSL and OpenSSL expects only trusted certificate authorities in the trust store (i.e. given with verify) and a server certificate is not CA certificate it will not help to add it to the trust store.
