It’s not a firewall issue – I can connect via port 80 to the server I normally have running on this machine. I shut that server down so certbot can bind to it, run the below command…but the verification fails and says it can’t connect to my server.
I have verified with dnschecker.org that the IP address for my domain is correct. Port 80 is available for certbot to bind, and it goes through my router/firewall fine when running the server I normally run on port 80. Why isn’t this working?
