TLS Cert Let's Encrypt Setup Incorrectly using http

For quite some time I’ve been getting `[ERROR] - Let's encrypt certificate issue exception` emails from the mailserver.

Taking some time today to look into it, I can see it’s saying the token is not available, and the url it’s providing is for http. I have http disabled, I proxy everything with valid certs but have this setup for potential direct connections I’m haven’t accounted for (via the mail ports).

Looking at the url myself, my browser correctly switches to https and the token is found. The correct protocol needs to be used/configurable to avoid this error.
