Current behavior

I tried to set to port 80 in settings.json, however, it will auto changed to port 81. Port 80 is empty and available, i would say the culprit live server doesn't have the permission (sudo) to use Port 80. How can I enable Sudo mode and use port80? I am trying to connect to other software and they are sending HTTP request only.
