For an unknown url - SSL Certificate error certificate verify failed: unable to get local issuer certificate (downloading data set )

I am working on a git-hub project in pycharm (Python v - 3.8) that generates a SSL Certificate, particularly for downloading a dataset. I tried the following method -
"import request requests.get('https://msd-for-monai.s3-us-west-2.amazonaws.com/', verify= False)"
It doesn't work and sends the same certificate error. I have tried all possible urls.
I want to know, if the url from which the error is generated is not known to us, how to solve the error issue.
And I am working from my office network with some restrictions

SSL error only in python command window with apify request

I am trying to use endpoint from apify.com. When I run my request in web browser with token everything is fine but if I run my request via requests library from python console I am getting following error:
SSLError: HTTPSConnectionPool(host='', port=443): Max retries exceeded with url: /endpoint?token=token (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1131)')))
Moreover if I set verify = False in my request than request is working. Does anyone have an idea what can be wrong? Thanks in advance

I had this issue come up a few weeks ago.
>>> pip install certifi
>>> python -m certifi
I'm not certain that one needs to actually call the module to get it's functionality, but I did and it solved the error. More info on Certifi here. It is also a recommended package extension to requests from their website. I added those lasts bits because I was wary of installing a package that ostensibly was never called after installation.

Solution was to install internal company SSL package for managing SSL connection from python. There was a recent change.

SSL certificate error - Jupyter notebook

I'm using requests in Jupyter notebooks to make a connection to 'https://dynamodb.eu-west-3.amazonaws.com/ (Amazon AWS) & have been getting the error :-
SSLError(SSLError("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",),))
It works with verify=False but I don't want to implement this due to security.
I've been googling solutions for days, trying to set REQUESTS_CA_BUNDLE from cacert.pem to weak.pem, setting SSL_CERT_FILE similarly, using certifi old_where instead of where, downgrading certifi, reinstalling requests with requests[security] - nothing has worked so far. I can connect fine via my browser, so it must be requests or Jupyter notebooks that has the problem or rather is missing the certificate.. I'm able to use requests to other https locations - I'm not sure if they are using SSL encryption or not. I don't know if I need to enable something in the environment or whether I need to get the AWS certificate into my environment variables (and also I don't know how to do either!)
Any help would be much appreciated! Thanks

Using SSL Certificates in Python2.7.*

I'm on a corporate network I need to use certificates for to get access to certain pages. I've tried looking around online for a module that'll retrieve an HTTPS webpage and also allow me to specify which certificate I want to use. I have this code:
import requests
page = requests.get("https://k9ballistics.com/",'lxml')
thing = page.content
thing = thing.split('\n')
for m in thing:
if '<tr>' in m:
print m
This works on retrieving a normal HTTPS page, but when I try to access our page it throws this error:
requests.exceptions.SSLError: ("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')],)",)
I was hoping to find a way to do it with a module that already comes with Python as opposed to relying on a pip installed package for portability's sake.
I'm on Windows, but I have my certificates from my linux workstation in a folder I'd like to point to, and also have Ubuntu Bash on Windows.

You can pass verify the path to a CA_BUNDLE file or directory with certificates of trusted CAs:
requests.get('https://eg.com', verify='/path/to/certfile.pem')
or persistent:
s = requests.Session()
s.verify = '/path/to/certfile.pem'
Also you can ignore verifying the SSL certificate by verify=False.
Have a look at SSL Cert Verification to see more details.

Python SSL CERTIFICATE_VERIFY_FAILED

I'm using the following code to interact with a Magento webstore using the XMLRPC api. Magento API Python XMLRPC
Everything was working ok until we made a change on our web server to SSL
Now I'm getting the following error.
ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)
I'm not sure why the certificate is failing as we have an EV certificate and all browsers are showing this as ok.
My connection string is:
How can I resolve this / over-ride the code
I'm fairly new to Python so please go easy :o)
magento = MagentoAPI("www.website.co.uk", 443, "myUsername", "myPassword", "/api/xmlrpc", True)

Python, or better the OpenSSL library it is using, can not verify the validity of the certificate of the server. There are many possible reasons: bad configuration, missing intermediate or CA certificate, wrong CN...
A first step could be to go to this site and let it test the SSL/TLS capabilities of the server: https://www.ssllabs.com/ssltest/
It will give you hints on how to solve problems as well.

Python verifies certs via its own bundle, check where it is located by
>>> import certifi
>>> certifi.where()
'/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-
packages/certifi/cacert.pem'
and add your certificates to the end of that file.
