    Test button never completes testing


      Hi all


      A VM is running Oracle 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?
