I don't have time to troubleshoot this for you but I think you have provided the server address twice (hostname and IP address), so it is being resolved as hostname:169.254.235.73:/opt/firebird/examples/empbuild/employee.fdb

Remove the "169.254.235.73:" out of the database path and it should work properly.
