SSL Cert Expiration Monitor on SAM Server Error

Just starting to deploy SAM and NPM for the first time. When I setup the SSL Certificate Expiration Date Monitor pointed at the SAM server it self it throws "Exception message is: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host"

Orion 2015.1.1, SAM 6.2 Hotfix1 NPM 11.5.1

Server 2012R2

Thanks!
