I have problem with getting ssl-certificate for server name olympmo.ru
The domain is accessable from internet by 80 and 443 (I have manually configured certificate for now)
On the same host I have also another nginx virtual host (server name) reg.olympmo.ru - and there no problem with certbot, it works.
Could you please check ip address for olympmo.ru in your DNS? It must be: 18.104.22.168. Because I'm not found the requests from certbot log in nginx log.
My domain is: olympmo.ru
I ran this command: sudo certbot --nginx
It produced this output:
Select the appropriate numbers separated by commas and/or spaces, or leave input
blank to select all options shown (Enter 'c' to cancel): 1
Requesting a certificate for olympmo.ru
Certbot failed to authenticate some domains (authenticator: nginx). The Certificate Authority reported these problems:
Detail: 2a03:6f00:6:1::57f9:26fd: Invalid response from https://olympmo.ru/.well-known/acme-challenge/mqvfgArB-XS7XewZLtNaJl8YkcJw2xYbOd7PUg0Ii2g: 404
Hint: The Certificate Authority failed to verify the temporary nginx configuration changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile /var/log/letsencrypt/letsencrypt.log or re-run Certbot with -v for more details.
