I tried to fix the above port settings based on the selected encryption here:

                this.propertiesPanel.form.findField('port')
                .setValue(value);
        }, this);

It is not working. Ports are still based/set on the old logic.
Is this the correct js script to look for or am I wrong here ?
How can I debug which js is being used and what is done ?

Thank you
