Need help with generating SSL cert for local web application with hostname “mydomain.iis.local”. I’m getting error: “The request message was malformed :: Error creating new order :: Name does not end in a public suffix”.
you can’t get a certificate with a private domain name.
You need a public visible and unique domain name to get a certificate.
So Letsencrypt can check that you are the domain owner.

Thank you, JuergenAuer!
You are asking for a public certificate for a private domain.
These are two distinct “systems” with distinct choices (choose one per domain):
- Use a private certificate [private CA] for a private domain.
- Use a public certificate [LetsEncrypt] for a public domain.
