Renew letsencrypt certbot certificate

[schoen]

@gotham

@hteo it shows client lacks sufficient authorization . Did you recently change document root of the site ?

Imgur: The magic of the Internet in this you can see Document root . did you change this after generating certs.

By the way, @gotham, this particular explanation of changing DocumentRoot after generating the cert is only relevant to the HTTP-01 challenge (for example using --webroot), but this error shows the TLS-SNI-01 challenge (for example using --apache). This authentication method doesn't rely on knowing the server's DocumentRoot.
