MagicMirror crashed due to "gnutls_handshake() failed: Error in the push function"

Hi,

This morning my MM showed a black screen and the pm2 log says following:

/home/pi/.pm2/logs/MagicMirror-error.log last 15 lines:

I did a search in the forum, but I could not find any other occurrences.
Will search the web now to see if I can find something more on this topic.
In the meantime any clue as to what happened is welcome.

Btw, a simple restart of MagicMirror solved the issue and my MM is working again.
Web search tells me that:

gnutls_handshake(): This function performs the handshake of the TLS/SSL protocol, and initializes the TLS session parameters.

Looks to be related with git, as all calls were done to github.com.
