Nagios Support Forum

Ah, of course that should be changed but unfortunately I still get the same timeout issue.

Yes, I'm available to connect to the https://server/nrdp address. Tried sending the check manually and I get an OK back but the nagios.log still says timeout.

Can you remove these 2 settings from the service check and see if the timeout is fixed?
