AWS DMS from On-Prem Informix to AWS MYSQL

I'm unable to authenticate/connect to local Informix server from AWS DMS endpoint.

**Here is the Error: **Test Endpoint failed: Application-Status: 1020912, Application-Message: Cannot connect to DB2 LUW Server Network error has occurred, Application-Detailed-Message: RetCode: SQL_ERROR SqlState: 08001 NativeError: -1336 Message: [unixODBC][IBM][CLI Driver] SQL1336N The remote host "Informix_server" was not found. SQLSTATE=08001

Which source Engine in Endpoint, I need to use to connect to Informix Server?
