Let's Encrypt - DNS01

Summary

Let’s Encrypt w/ DNS-01 validation

Observed behavior

Is it possible to use the built in Let’s Encrypt integration with DNS 01 validation? This is for an internal Mattermost server running on Ubuntu 18.04, it will never see the web, so I don’t want to open 80 or 443.

Hi @rshah, No, DNS-01 is not supported, as it’s not supported by https://godoc.org/golang.org/x/crypto/acme/autocert.
