Web Application Availability Monitoring Test Timeout

Dears,

I have a strange problem that I didn't find any similar issue in the internet,

I want to monitor some internal SharePoint 2010 web sites on the web front ends using SCOM 2012 so I created a new Web Application Availability Monitoring template to monitor the internal URL on the WFE servers but it's not working and when I try to run the test it times out without running on the servers and I didn't find any events that can help.

I also tried to monitor http://www.google.com but the test is also not running..

Please help,

Thanks,

A Seyam
