I set up a Nextcloud Server via Nextcloudpi on a Raspberry Pi. I did that after my old configuration (nextcloud snap) stopped working after a software update on the Raspberry. The point is that I did not change port forwarding settings in my router worked. My DNS Server receives the correct IP address. I also tried
sudo ufw enable 443 without success. Nonetheless, I get a “likely firewall problem”. What else can I do?
My domain is: https://ericsowncloud.ddns.net
I ran this command: NextcloudPi Configuration / Networking / letsencrypt / Start.
It produced this output:
Running letsencrypt Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator webroot, Installer None Obtaining a new certificate Performing the following challenges: http-01 challenge for ericsowncloud.ddns.net Using the webroot path /var/www/nextcloud for all unmatched domains.

Additionally, please check that
your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.
The operating system my web server runs on is (include version): NextcloudPi (Raspbian)
