We have configured CA Access Gateway(SPS) R12.52 at frontend and CA Virtual Appliance(Vapp) R14.2 where IAM is running at the backend. 

We have created the proxy rules to forward/redirect the request from CA Access Gateway(SPS) to CA Virtual Appliance(Vapp).

When we try to access the backend resource via the proxy server, we get the below error message:
Request URI : /iam/im/identityenv/ 
Error Type : SPS Exception 
Error Code : Noodle_GenericException 
Message : Indicates error at noodle stage. More detailed in SPS logs. 

After enabling SSL logging as described below, the below errors were reported in the Access Gateway server.log:
