Hello,

When a try -ssl=on on a site, I get this error on the log (file and directory permissions are ok, and when I manually create /var/www/[domain]/htdocs/.well-known/acme-challenge/4p5hH4DSLWfSeHHHFYqpSO4Tn-h8CFYJ828aBDrWK3U I get the same 403 Forbidden error):

Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:
  Domain: www.[domain]
  Type:   unauthorized
  Detail: Invalid response from http://www.[domain]/.well-known/acme-challenge/4p5hH4DSLWfSeHHHFYqpSO4Tn-h8CFYJ828aBDrWK3U [161.35.140.234]: "<html>\r\n<head><title>403 Forbidden</title></head>\r\n<body>\r\n<center><h1>403 Forbidden</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.

In the php error log I get:

2021/06/08 07:07:54 [error] 967#967: *1664 access forbidden by rule, client: [my ip], server: [domain], request: "GET /.well-known/acme-challenge/4p5hH4DSLWfSeHHHFYqpSO4Tn-h8CFYJ828aBDrWK3U HTTP/1.1", host: "[domain]"

Any hint in the right direction would be appreciated

Found de issue: a rule in a custom-nginx.conf file to prevent returning hidden files (created by following instructions of Defender Pro).

Glad you found a solution!

In fact, Webinoly has all these security rules already included, you don't need any additional rules, unless you have something very specific.
