Any idea?

Hi Jorge,

The ssl-setup script generated a self-signed CA which is generally untrusted. If you import ca/certs/cacert.crt as a Trustpoint into the Browser on your remote machine, it should work.Which browser are you using?

Another way forward is to used a certificate created by a trusted certificate. For example, using Let’s encrypt you can create certificates for free, however, these certificates have a limited validity time and an automated procedure should in place to renew/update certificates.

Note, however, the post is fairly old and the snippets may no longer works oob.
