IO Error 17002 in Oracle SQL Developer

947107Aug 5 2012 — edited Aug 6 2012

Hi,

I am trying to connect to the test database using the Oracle SQL developer but I am getting the below error
IO Error: The network adapter could not establish the connection vendor code 17002

I used to connect to the test server fine 2 weeks ago (the test server is on another network and i connect to it using the VPN).

I am able to connect the the Production Database through the Oracle SQL developer (without VPN) but when I try to connect to the test i am getting the error.

I have checked the service name and ports and everything is fine and. So what could be the problem?
