Nagios Support Forum

I have successfully installed NAGIOS XI. I am not able to connect using the URL http://<server_address>/nagiosxi to finalize the installation. Page not found is the error. I have searched and unable to find a document describing the starting of the application server.

Hello @jjk94,

Since this is your first post and I'd like to thank you for choosing Nagios! We're happy to have you in the community. It ought to come up, let's check a few things.

1. What is the operating system you installed on and was this a clean install (anything else running on the server)?

2. Are you able to successfully ping the server from your workstation? 3. Is Apache and the Nagios process running? 4. Are you able to access the Nagios Core interface?

systemctl status httpd - Not Running
I did start and can access the redhat apache default page
