    Test button never completes testing

    user12997323

      Hi all

       

      A VM is running Oracle 12.1.0.2.0 and sqlplus connects to the TNS alias ORCL.  However, when trying this on SQL Developer 17.2 (also 4.1) the test button shows the testing screen until after a long time the message is

      Status : Failure -Test failed: IO Error: Socket read timed out

       

      Any help?

       

      Thanks

      AA
