git clone fails with gnutls_handshake() failed error in the push function

git clone https://github.com/waveform80/pistreaming.git fails as noted on my new RPi Zero W

A different git clone done moments before worked fine:
git clone https://github.com/silvanmelchior/RPi_Cam_Web_Interface.git

Any ideas on what's wrong and how to fix?

worked using sudo git clone https://github.com/waveform80/pistreaming.git
suggest adding "sudo" to the installation instructions.
