Even if I hit ip in the browser, nginx is not displayed and I am in trouble.

nginx -v nginx version: nginx/1.11

firewall settings

sudo vi /etc/firewalld/services/ssh.xml
<? xml version = "0.0" encoding = "utf-8"?>
  <description>Secure Shell (SSH) is a protocol for logging into and executing commands on remote machines.It provides secure encrypted communications.If i plan on accessing your machine remotely via SSH over a firewalled interface, enable this option.You need the openssh -server package installed for this option to be useful.</description>
  <port protocol = "tcp" port = "12345" />

Executed below

sudo firewall-cmd --reload
sudo systemctl restart sshd.service
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: eth0
  services: dhcpv6-client http ssh
  ports: 12345/tcp
  masquerade: no
  rich rules:

We are also implementing:

The status is normal.

systemctl status nginx

The response time is too long even if you type ip160.160.160.160 on the browser.
