Hello,
You seem to have a redirect with mail.ambiente.one and my.ambiente.one.
As a consequence, the letsencrypt server couldn’t find the file it needed to check that you do have ownership of this domain.
You’ll have to configure your web server to deactivate the redirection on /.well-known/acme-challenge.
For apache configuration check this post [Webroot] Only performs http-01 challenge which doesn't follow HTTP redirects to HTTPS site
