Nextcloud Clone - Neues Letsencrypt Zertifikat

[CRO]

Hello,
I created a clone of our Nextcloud. As a result, the FQDN has also changed.

Now I want to change Letsencrypt’s certificate.

With the command:
sudo certbot --apache -d neuer-servername.de

I get the error message:
The Certificate Authority failed to verify the temporary Apache configuration changes made by Certbot. Ensure that the listed domains point to this Apache server and that it is accessible from the internet.

Port 80 is accessible from outside.

What do I have to change so that I can adapt the Letsencrypt certificate to the new domain?

Thanks
Chris

@CRO

sudo certbot --apache -d neuer-servername.de

Did you create the first certificate this way as well?

The question then would be, what has changed in your apache configuration that certbot’s modifications don’t work anymore.

Thank you!
I have solved the problem. I had a problem with the firewall.
