Finally after hitting "Apply" getting - "Waiting for configuration verification" forever; seems to go into a never ending loop

Do any of these KB articles help resolve your issue:

https://support.nagios.com/kb/article.php?id=532

thanks so much sir.

https://support.nagios.com/kb/article.php?id=34
is most relevant and I did everything that the article said but problem persists.

"Waiting for configuration verification..........."

Can you run the following in an ssh session on your Nagios XI host.
Then go into XI and Apply Configuration.

What output is produced in the SSH session?

Thanks so much for trying to help.

Output of "tail -f /usr/local/nagiosxi/var/cmdsubsys.log" & other commands like "netstat -tulnp | grep 80", "nmap localhost" is below.

Looks like the applyconfig is failing, possibly due to the localhost resolution.

Can you post your /etc/hosts file, and also a screenshot of your Admin -> System Settings page?

Attaching Admin -> System Settings

root@vps-cl0:/home/vps# more /etc/hosts
127.0.0.1 localhost vps-cl0
127.0.1.1 vps-cl0

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

The issue is it's trying to access localhost on port 80, not 4321. Take a look at the file /usr/local/nagiosxi/html/config.inc.php.

Does it work now?

Thanks rkennedy; it worked like a charm.

THANKS LOTS.

Glad we could help! I'll be closing this thread now, but feel free to open another if you need anything in the future!
