Load runner not allowing Ocale forms page

I am currently scripting Oracle Financials application
We have forms Version: 10.1.2.3.0
Applications Version: 12.1.2

When i replay my script i cannot access the Forms.
Action.c(233): Error: nca_connect_server: cannot communicate with host XXXXX.devtst.XXXXX.com on port XXXX

Any ideas or thoughts
