Hi @eugenetedkim,

I can see your domain is properly pointed to your DNS and it’s actually pinging from it. It seems the issue is you’ve closed port 80 and 443 and thus getting this error message - connection refused.

Firstly, in order for the ports to be opened, something would need to listen to them. On port 80 and 443 usually what listens to them are services like Apache/Nginx. They are used to process the requests on the server and server the websites on it. Having said that, please make sure you have either Apache or Nginx installed and configured.

If you are unsure how, you can check the following articles:

Install and configure Apache

Install and configure Nginx

Firewall

• If you are using UFW, you can execute

sudo ufw allow 80
sudo ufw allow 443

• If you are using only IPtables, you can execute

iptables -A INPUT -i eth0 -p tcp -m tcp --dport 80 -j ACCEPT
iptables -A INPUT -i eth0 -p tcp -m tcp --dport 443 -j ACCEPT
