How can we fix this issue?

Environment

  Web Agent R12.52 SP1 CR07 64bit on IIS 8.5 64bit on Windows 2012

Cause

  The health checks from your load balancer monitoring tool is sending the request without the HOST header

Resolution

Configuring the load balancer properly to set the request with HOST header will solve this issue.
