Recent issues "Internal errors"

[damnshaneisthatu]

Have been using Nginx Proxy Manager for over a year now, but have recently faced issues renewing certs.

What I'm seeing in the logs:

Command failed: certbot certonly --config "/etc/letsencrypt.ini" --cert-name "npm-4" --agree-tos --authenticator webroot --email "[email protected]" --preferred-challenges "dns,http" --domains "nextcloud.shaneermitano.com"

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Some challenges have failed.
