Nagios windows client services are give me error of "CRITICAL - Socket timeout "

Hi All,

I have configured the Nagios server on Centos 7 and added a windows' client on it. But when i checked the services on the dashboard of nagios it says "CRITICAL - Socket timeout". It looks like there is a communication issue. Therefore, I check the firewall on both the machine and able to see that firewall is in stopped state. Also, I have check the suggestion from internet and try to fix it but nothing works
if anyone has faced same issue and having any solution please share

one Client machine: 12489 and 5666 is open and listening
