Hi @Yaniel

checked your url with my browser:

  • there is a redirect (normally, that shouldn’t be a problem),
  • but: There is a client certificate request. If I click “Esc”, I am blocked.

Looks like you have configured your webserver, so client certificates are required.

So Letsencrypt can’t check your validation file.

Remove that.

PS: Checking your url directly there are curious redirects -

redirects to

Looks like you have some broken redirect rules.
