Hello,

I am a new user on Nagios core and it was working good till last week but now when i am trying to access the web interface of it the connection is failing and the browser says "The system returned: (113) No route to host

The remote host or network may be down. Please try the request again". Nagios core is installed on Centos.

Thank you

Can you SSH into the server?

Try running this command:

Code: Select all

curl localhost

Are you accessing via IP or DNS name?

What is the output of this command:

Code: Select all

netstat -rn

Thank you

Also, run this command:

Code: Select all

tail -f /var/log/httpd/*error_log /var/log/httpd/*access_log

And let it run and then try to connect to the web interface and attach the output so that we can review it.

Thank you
