Nagios Support Forum

Hi,

I've noticed that a large majority of our servers are randomly reporting "nrpe[3301]: Error: Could not complete SSL handshake. 5 " in the client logs which causes checks to enter a CRITICAL state with the following error:

Additional Info:

CHECK_NRPE: Socket timeout after 10 seconds.

I've been unable to track down the cause of this issue since it's so widespread. Is there a way to perhaps disable SSL handshaking on our Nagios server? If anyone has experienced this issue and has any ideas, please share.

Thank you!

You should be able to use the -n flag.
