Expo Go algo salió mal respuesta de la red de la red

What solved this for me was simply changing the connection from LAN to Tunnel. 
When you start an expo app, 
a browser window will open with a URL like http://localhost:19002/. 
Along the left side is a Connection option set to LAN by default. 
Changing it to Tunnel before scanning the QR code with the expo app solved it.
