[New-bugs-announce] [issue34440] Certificate verify failed (works fine in 3.6)

[Lennart Grahl]

New submission from Lennart Grahl <lennart.grahl at gmail.com>:

When running the attached script with the attached cert, Python 3.7 raises an exception (see https://paste.pound-python.org/show/VLr84Yn2Fnz6RSKEq3ui/). In Python 3.6, the certificate is being accepted.

I don't see anything wrong with the self-signed certificate.

You can (hopefully) reproduce this by running minimal_server.py
