AttributeError: module 'lib' has no attribute 'X509_V_FLAG_CB_ISSUER_CHECK' while running certbot

Getting this stack trace when running certbot with a DNS challenge (dns-azure):

Am running this from the nginx-proxy-manager, but I saw this container is the base container with certbot so figured it was the appropriate place to raise the issue.

From looking up the stack trace, it seems to be related to a dependency mismatch in pyopenssl:

Getting a shell in the container and activating the certbot venv then updating pip and pyopenssl immediately solves the problem (at least until next pull / redeploy). I was happy to put up a PR to include pyopenssl in the pip install for Dockerfile.certbot but I didn't want to create any potential knock on effects for things I may not be aware of, so just reporting it first.

source /opt/certbot/bin/activate
pip install pip --upgrade
pip install pyopenssl --upgrade
