What do you see, when you try to access nagios by typing in the browser's address bar? Log in screen, blank page, etc.?

http://<ip address>/nagios

Can you check the apache error log once more for errors?

Code: Select all

tail -50 /var/log/httpd/error_log

[tmcdonald]

Run this from the command line of the nagios server and post the output:

Code: Select all

curl -I 127.0.0.1
curl 127.0.0.1

[rlevick]

Here is the response from http://<serverIP)/nagios
The connection has timed out

The server at 10.100.40.70 is taking too long to respond.

The site could be temporarily unavailable or too busy. Try again in a few moments.
