When I go to http://sub.example.com in my browser I get a "connection refused" message or an "invalid certificate" error but I don't even want to connect over https.
As far as I know:
- The web server is configured correctly for
sub.example.com - TCP port 80 is opened in the firewall/security groups
- plain HTTP and not HTTPS is used in the URL
- the DNS record for
sub.example.compoints to the correct IP-address of the web server - the web server was restarted with new configuration
- the logs don't show start-up or any other errors
How can I debug and what is the problem there?
