@dreid hey, I hope you don't mind me asking this here - how would you go about setting SSL_OP_IGNORE_UNEXPECTED_EOF to True via the pyopenssl api? I'm running into this error with openssl and I think the reason is I need this flag to be true urlopen error TLS/SSL connection has been closed (EOF) (_ssl.c:997)

From the eventlet test suite:

Edit: I see that you "fixed" your release and made clear that cryptography needs to be at 0.38.0. Then the error won't happen.

This still happens with cryptography 0.38.1
