State: CRITICAL
Info:
(Service check timed out after 60.01 seconds)

Hello @ssirnagiosadmin!

Welcome to the Nagios Support forum.

It appears that check has timed out. However, there can be many reasons that a check will time out.First we will need to know what check Nagios is trying to execute. Navigate to the Configure section using the bar on top > click Core Config Manager under Advanced Configuration on the left pane > then click Services under Monitoring on the left > then click on the service specified in the notifications > and let us know what command is specified in the Command view part of the Service Management page under the Common Settings tab.

To help troubleshoot, you can also directly test the service check from the command line, to see if you get the same behavior. We have instructions on this procedure below. Please post the output for us to review.
TEST CHECK COMMANDS FROM TERMINAL
