Cause: Affinity has been configured on the Basic History Service and neither the IM or All Nodes has been added to the Affinity Definition Aspect. The result is that requests for IM data can not be directed to the IM because Affinity prevents it. Resolution: 
Either add All Nodes, as shown below, or IM node to the Affinity Definition Aspect that is assigned to the Basic History Service. Requests will begin working right after the aspect changes are applied.
