A Network Load Balancer is preventing the connection to the front end servers.
Add an entry in the Hosts file (C:\Windows\System32\drivers\etc\hosts) of your Spotlight on Messaging Server so that the IP address of the pool will resolve to a Front End Server and not the Network Load Balancer.
The entry should be in the format "IP address [TAB] FQDN of Pool".
