Josh Rosenberg added the comment: Are you 100% sure your CA files is in the precise PEM format required by Python for CA certs, as described in https://docs.python.org/3/library/ssl.html#ssl-certificates ?
The most likely cause of your failure and success would be if you were using some other cert format that Windows could load that wasn't PEM. Also, side-note, you messed up your path when you attempted to anonymize it (you omitted the backslash after C:). Of course, you didn't anonymize it in the error output, so I can tell the original path was not messed up. ---------- nosy: +josh.rosenberg _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21830> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
