I recently bought a MacBook and migrated to macOS from Ubuntu. The surprise happens when I run sshuttle and begin ssh-tunneling in my mac. In Ubuntu, my adb continues to work perfectly but it's in macOS that adb stops working with the error error: protocol fault (couldn't read status): Undefined error: 0.
In my case, the problem was due to sshuttle. sshuttle automatically forwarded also localhost requests so the connection to adb was lost.
I cloned the repo and went back to ef83a5c and built the program again. this bug was found approximately two weeks ago partially fixed once and now it's again under development.
git clone https://github.com/sshuttle/sshuttle.git
git checkout ef83a5c
sudo ./setup.py install
