Hello I am facing the same issue
port is opened on server and in security list
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_TIMED_OUT
If I ping domain name from terminal, it resolves to server ip correctly
Edit:
It worked after adding following entries to iptables
sudo iptables -I INPUT -p tcp --dport 80 -j ACCEPT
sudo iptables -I INPUT -p tcp --dport 443 -j ACCEPT
