Since there are no suggestions, how can I upgrade OPENSSL in a safe way. It seems that another problem I had before (upgrading dovecot) had the same issue, so it would be great to upgrade OPENSSL

Hi that error sometimes happens when files underlying the lets encrypt extension are updated.
Have you tried uninstalling the extension and reinstalling?

cheers, Tom

Try to use this command line your issue may be fixed.

• Go to your server's shell as root
• cd /usr/local/psa/var/modules/letsencrypt/venv/bin
• ./pip install --upgrade cryptography
