IIo exception error when trying to reset an Oracle RDS account password

Hello.  trying to set up an AWS RDS Oracle database connection in PMP

When I try to reset (or automatically when checked in) I get the error below.

Io exception: The Network Adapter could not establish the connection

Port and DNS is correct.

Using the Oracle DB Server resource.  

Should I use a different resource type?

Thanks
