Check your firewall, if it’s blocking port 443.

Also check that apache is actually listening: ss -tlpn | grep :443 (if it’s not, restart apache)

Check that your virtualhost actually exists: httpd -S

hi thanks for the reply , can ask how to check firewall blocking port 443 or not ? thanks apache is listinging to 443 , and httpd -s is existed

I have no idea, there can be firewalls at different levels, on your machine, at your cloud provider…

look like port 443 is not opened yet thanks for information
