Let's Encrypt requires (according to documentation I have seen) Port 80 TCP be in use for verification. I have no other legit use for Port 80 on this smart host and decided a long time ago, not to use Let's Encrypt for that reason.
That's true for the HTTP-01 challenge type, but Let's Encrypt also allows the use of other challenge types.
The DNS-01 challenge protocol verifies domain ownership through DNS by having you add a TXT record to your domain for each certificate request.
I found it a bit annoying to automate it but it's a better setup for me than running a bunch of otherwise-useless http servers.
See https://letsencrypt.org/docs/challenge-types/ for more information. _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
