Random disconnections like this are usually caused by Bluetooth interference or low battery. A few things worth trying: make sure there are no other Bluetooth devices nearby competing for signal, keep your phone or laptop close to the toy during your stream, and check that the toy is fully charged before going live. It can also help to re-pair the Lush 4 in the Lovense app and make sure you have the latest firmware installed.
