Connection Timeout while connecting to GATT Service on Android Device

Hi,

I setup a simple GATT TimeService 0x2A2B : 0x2902 with nRF Connect on Android (Nexus 5X).

Trying gatt.connect() with the following simple script from puck results in Connection Timeout:

NRF.findDevices(function(devices) {
    console.log(devices[0]);
    devices[0].gatt.connect().then(function(g) { 
        g.disconnect();
    });
}, 3000);

Any hint?
