Hi Ioan,

I have _ **no** _ knowledge about certbot, but I'm about to announce a new LetsEncrypt node for Node-RED. So I have been playing with the acme protocol already, which hopefully can get you a bit started ...

- When you _ **request a new certificate** _ for a domain ([mydomain.com](http://mydomain.com)), the guys from Letsencrypt have to be sure that you are the owner of [domain.com](http://domain.com). Otherwise everybody could request a certificate, which means it wouldn't be secure anymore ...

- Once you have received your Letsencrypt certificate, that certificate should be used by your webserver when you connect to Node-RED:

Good luck!  
Bart
