I know my DNS records are correct because all my webservers work. I have Apache 2 and it works fine. Running discourse-setup it claims:
*Hostname for your Discourse? [discourse.example.com]: list.pteranodon.space* *Checking your domain name . . .* *WARNING:: This server does not appear to be accessible at list.pteranodon.space:443.* *A connection to http://list.pteranodon.space (port 80) also fails.* *This suggests that list.pteranodon.space resolves to the wrong IP address* *or that traffic is not being routed to your server.*
But none of this is true. I am a Discourse newbie. What have I got wrong?
