Resolved Port 80 closed?!

[LMAR6]

Hi!

I'im installing a new server and got a strange problem. The hosting accounts are not reachable due the closed port 80.

1) Why is this port closed? It's just Cloudlinux 7.3 + Plesk Onyx 17.0.17 Update Nr. 15 , nothing changed during installation...

2) I can't open Port 80.

• disabled included firewall from webhoster
• plesk firewall app: WWW server Allow incoming from all
• iptables: ACCEPT tcp -- anywhere anywhere tcp dpt:http

What else could be blocking port 80? How can I debug this?

Ports tested with dnstools.ch and Nmap.

Thanks in advance.

What is the output of
# netstat -plnt | grep ':80'
?

You are using Nginx as reverse proxy. Your ports 7080 and 7081 are active, they are the upstream ports of Nginx->Apache. But The default Nginx web server ports are not active. Probably Nginx is not running or misconfigured.

Can you please check whether Nginx is running?
# service nginx status

If it is not running, please start it by
# service nginx start

Thank you! I should have known that...Problem solved

The restart of nginx worked. I will now check the reason for the failed start after the last reboot. But I think, I can do this on my own
