HTTP-KeepAlive was disabled, once enabled communication started to continue.
Http-keep alive is required because the agent follows the head method with the post, while IIS was terminating the connection, causing the error on agent side (0 length response)
Upon checking the TCP-stream for GetClientPolicies.aspx from a client, we found that the connection was closed from server side just after the head method from client, causing the server not to respond to the followed post method in the same stream.
Turn on Http-KeepAlive
IIS manager, Default Web Site, HTTP Response Headers, Set Common Headers: Check box "Enable HTTP Keep-Alive"
