Ok, found the issue with 3. -- it works just fine on Sierra, but there is a bug in El Capitan which fails to accept 127.0.0.1 in the ATS exception list so it's in fact impossible to white-list it. Apple has fixed that bug in Sierra but not in El Capitan, so I have added a work-around by forcing the use of localhost instead. I have also kicked-off another build so the latest RC with the fix (GUI r7337) should be up in another 15 mins at http://R.research.att.com.
