Nginx Proxy Manager Version 2.9.14

To Reproduce Add Let's Encrypt Certificate with wildcard

Workaround: Access NPM container and install dnspython package:

docker exec -it [container] bash
pip install dnspython

I've made this more generic and grouped it with https://github.com/jc21/nginx-proxy-manager/issues/1535.
It seems sometimes certbot plugins just do not install some dependencies? In this case it was the duckdns plugin, which definitely has dnspython as a requirement.
Furthermore this issue seems to only occur very rarely, as I only know about the one report (by two people) before.

I had the same issue. After manually pip3 install dnspython also an wildcard certificate from DuckDNS is working. So please fix this issue.

I have the same error:

[1/10/2022] [8:44:43 PM] [SSL ] › ✖ error Error: Command failed: certbot renew --non-interactive --quiet --config "/etc/letsencrypt.ini" --preferred-challenges "dns,http" --disable-hook-validation

An unexpected error occurred:

ModuleNotFoundError: No module named 'dns'

EDIT: pip3 show dnspython showed that the package is missing. I have tried to redeploy the container which did not help. pip3 install dnspython fixes it as mentioned above
