No web interface display

Post by pnhelgren »

I have read multiple posts about this issue but cannot find a solution. I have a Nagios Core 4.4.6 running on OpenSuse Leap 15.3 on PPC64. The web page WAS rendering just fine and then in trying to sort out an issue with a plugin, it stopped working. I can't remember what I had done, but the web interface no longer renders.

Nagios is running because I do get email notifications when a service has an issue. Apache is running fine because I have other web-based services that will display their web interfaces. I know that the vhost is being hit because when I initially hit the web URL, I am prompted for the nagiosadmin credentials and they are accepted.

The logs show nothing of great interest (I bounced the service which is why there is a shutting down and a resuming entry):

I suspect this is self-inflicted but I can't seem to get to the root cause of the issue. I don't see any errors yet something is clearly wrong.

Suggestions?
