Hi @v.sollier

which domain name did you used?

You can only create a certificate with a public visible, worldwide unique domain name.

You can't create a Letsencrypt certificate with localhost or something else as domain name.

Hi @v.sollier,

Can you share the exact command you ran when you got this error message? If @JuergenAuer's idea that the domain itself is invalid isn't correct it's possible that you entered the domain name in your command in a way that is causing the error.
