SSL Error when attempting to connect to the BOX API

[mklem76]

Hello - I am trying to create a python executable file that leverages the boxsdk login code. When I attempt to run the executable on my computer (python install) and my coworkers (Python not installed), I get the following error:

requests.exceptions.SSLError: HTTPSConnectionPool(host='api.box.com', port=443): Max retries exceeded with url: /oauth2/token (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1131)')))

Even when I was leveraging the boxsdk in jupyter notebook i would get this error. I fixed it by changing my default browser from Google Chrome to Mozilla Firefox.

Do you have a way to get around this certificate issue with the BOXSDK?

Hi @mklem76,

This is probably due to some proxy server in your company.
Your code not works from chrome and from executable file because chrome using system's network settings, where you probably have set some proxy settings. But It works on Firefox because it sandboxex the proxy connection and restricts it only to the specific browser window.

The approach we would recommend here is to get the certificate that's being injected by your proxy and set the REQUESTS_CA_BUNDLE environment variable to the path to that certificate (or a directory of CA certificates) when running your program.
The second approach which we do not recommend because it is insecure is to disable all SSL validation, you can set the PYTHONHTTPSVERIFY environment variable to 0.

If you are not sure about the proxy certificate please contact your administrator for help.

Hope this was helpful!
