I cant Pass the domain checking

am trying to use ./discourse-setup ,but i got problem

Checking your domain name . . .
WARNING: Port 443 of computer does not appear to be accessible using hostname:  www.doublekm.xyz.
WARNING: Connection to http://www.doublekm.xyz (port 80) also fails.

This suggests that www.doublekm.xyz resolves to some IP address that does not reach this 
machine where you are installing discourse.

The first thing to do is confirm that www.doublekm.xyz resolves to the IP address of this server.
You usually do this at the same place you purchased the domain.

If you are sure that the IP address resolves correctly, it could be a firewall issue.
A web search for "open ports YOUR CLOUD SERVICE" might help.

This tool is designed only for the most standard installations. If you cannot resolve
the issue above, you will need to edit containers/app.yml yourself and then type

./launcher rebuild app

the port and firework

[root@GreenCloud discourse]# netstat -lnptu | grep :443
[root@GreenCloud discourse]# netstat -lnptu | grep :80

[root@GreenCloud discourse]# firewall-cmd --permanent --list-ports
8080/tcp 8079/tcp 80/tcp 443/tcp

If you read the discourse-setup script, there is a command line switch you can add to skip that test. (I think it was --skip-tests)

I don’t see a reason that it’s failing, I think it tests to make sure that the pieces that it uses to do the test are installed.
