Does not work on clean Raspbian Stretch, had to install Jessie

[lukdz]

I follow your tutorial, but it didnt work, then I try to install your Docker, but it also didnt work. MacBook/Android keept failing to connect, and raspberry after delay declared peer dead.
When I tired with Jessie it work first time.
