Hi, I have problem trying to renew certificate on my server.
I've received such error message:
Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
Detail: Invalid response from http://mail.domain.com/.well-known/acme-challenge/YWCQsuJcIsEyFIeKW8mljDvcoe5HSmII_RddMSiG3ZA [ip_address]: "\n\n400 Bad Request\n\n
Hint: 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.
Could not find the solution when I tried to google it.
