The error message is self explanatory. Your certificate isn’t valid. It needs to use the SubjectAlternativeNames field (SAN).

I don’t understand what you’re trying to say.

Either way, Caddy doesn’t support invalid certificates.

Specifically, CommonName has been deprecated for 23 years, and this error message comes from the Go standard library because it is no longer a supported field.
