In order to troubleshoot we'd need too see your check-host-alive command. Sounds like something is improperly configured there.

Nothing is wrong, your router simply is either down, or your Nagios box is unable to ping it.

Nothing is wrong with your configuration. The "error" is realy - connection refused when your Nagios server tried to open a TCP connection to your ssh daemon on that host.
