My domain is: http://stage1.businesstagebuch.de/
I followed the guide: https://certbot.eff.org/lets-encrypt/ubuntufocal-nginx
Before I ran that command, I stopped Nginx
I ran this command: sudo certbot certonly --standalone
It produced this output:
Obtaining a new certificate
Performing the following challenges:
http-01 challenge for stage1.businesstagebuch.de
Waiting for verification...
Challenge failed for domain stage1.businesstagebuch.de
http-01 challenge for stage1.businesstagebuch.de
Cleaning up challenges
Some challenges have failed.
In the log /var/log/letsencrypt/letsencrypt.log
I see:
