    IO Error: The Network Adapter could not establish the connection

    aa9e61b7-9082-4c39-b16f-aa067b8b705d

      I accessed SQL Developer fine on Friday and opened it today and got this error


      ("An error was encountered performing the requested operation:
       
      IO Error: The Network Adapter could not establish the connection
       
      Vendor code 17002")


      I am using an IP address for the hostname and pinging the server works fine. These are suggestions for other errors associated with the same vendor code. Anyone have suggestions for Network Adapter connection establishing? I am using a VPN but am connected successfully just as I was when this ran successfully. I have also added a firewall exception for this port just to make sure.


      Thank you!
