Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:
Domain: portal.comp-moto.com
Type: unauthorized
Detail: Invalid response from https://portal.comp-moto.com/.well-known/acme-challenge/Gg4p39t4hYEVTTby41i166mNjwGq-1jh-KqGsyffIUg [103.86.51.196]: "<html>\r\n<head><title>404 Not Found</title></head>\r\n<body>\r\n<center><h1>404 Not Found</h1></center>\r\n<hr><center>nginx</center>\r\n"
Hint: The Certificate Authority failed to download the temporary challenge files created by Certbot. Ensure that the listed domains serve their content from the provided --webroot-path/-w and that files created there can be downloaded 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.
