[SOLVED] Let's Encrypt website security disabled

After updating on trixie I have an issue with let’s encrypt. Website security is disabled (Deaktiviert). I did rerun installation from the backup, but the issue did not disappear.

This is how the status in System looks like:

The error is following:

 Fehler:
Fehler beim Beziehen des Zertifikats für Domain xy.ch Details

Error running action: letsencrypt..obtain("xy.ch"): CalledProcessError(1, ["certbot", "certonly", "--non-interactive", "--text", "--agree-tos", "--register-unsafely-without-email", "--domain", "xy.ch", "--authenticator", "webroot", "--webroot-path", "/var/www/html", "--renew-by-default"])

What is the next step? How can I get let’s encrypt to work again?
Thanks for some advice!

As I did rerun Diagnostics the Name Services showed an error on resolving debian.org. I tried to figure out the problem and therefore I changed the DNS settings on Name Services from Opportunistic to No. After this I did repair Let’s Encrypt with the repair button and now everything is working :slight_smile:
