Zammad installlation is not successful on Rocky Linux 8

[suresh]

• Used Zammad version: Latest
• Used Zammad installation type: Package
• Operating system: Rocky Linux 8
• Browser + version: Chrome Latest.

Expected behavior:

Should see the home page on browser, but not seeing. I’m trying to access it using IP, not domain.
IP with port number - 3000. http://xx.xx.xx.xx:3000.
Could see the nginx default page on standard http port 80 - http://xx.xx.xx.xx, but can’t see zammad page at port 3000.
I’ll attach the domain later.
*

Actual behavior:

• Can’t see the zammad home page at port:3000 with IP.
  The port 3000 has been whitelisted already, but the Browser says refused to connect.

Steps to reproduce the behavior:

• Installed using official doc - Install from package — Zammad System Documentation documentation
  and https://techviewleo.com/install-and-configure-zammad-helpdesk-on-rocky-almalinux/?expand_article=1

Is it work with domain name only? but not with IP?

Remove the default vHost file and adjust the zammad.conf as needed.
Then reload nginx by using systemctl reload nginx and you should be able to access the Zammad WebUI via https. Please consider not using Port 80 (http) as sensitive information is being transferred.-
