Nagios Monitoring Error

[wipro-cloud-services]

Team,
Nagios is not monitoring the servers which are already configured. PING connection shows "OK" but remaining all shows "CRITICAL - Socket timeout after 10 seconds" and "Connection refused" error.
Our license has expired. Can you please let us know if the root cause of this error is license expiration or Configuration problem.

Warm regards,
Sumanth

I don't believe this sounds like a licensing issue, it actually sounds like either a configuration issue, and possibly a firewall issue.
