HFM is not working with scan ips

We are using  Hyperion v11.1.2.x and datsbase is installed on 4 node RAC with scan ip.database version 11.2.0.3.

orignal JDBC connection works fine for FOUNDATION shcema.Another piece he has to install in HFP_HFM schema and that uses TNSNAMES.ora and that's the part that is failing.

We are using scan ips in our connect  string.Please guide us for proper connect string  to use r SCAN ip with Hyperion application.

Error from config tool.
