Why was I disconnected while streaming?

Almost always the internet connection: streaming pushes data upstream continuously, and upload is the weakest part of most connections. Wifi hiccups, other devices hogging bandwidth, or your ISP wobbling all cut a stream. If your connection is genuinely fine, check whether your device was throttling the app: closing the streaming tab, phone sleep, or aggressive battery savers all stop the broadcast.

The usual causes

Upload bandwidth dips: streaming needs a steady upstream. Downloads elsewhere in the house, cloud backups, and game updates all steal it.
Wifi instability: walls, distance, and interference cause micro-dropouts that kill a live connection. Wired beats wifi for streaming, always.
The device throttled you: phones pause apps in the background and under battery-saver, and closing the browser tab you stream from ends the broadcast.
Overloaded hardware: if the device is maxed out running the game plus the stream, the encoder starves and drops.

Making it stick

Use ethernet if you possibly can; if not, stream close to the router on 5GHz wifi.
Keep the streaming app or tab in the foreground, plugged in, with battery saver off (mobile).
Quiet the network: pause downloads and backups on other devices while live.
Let quality adapt: VERGR measures your connection when you go live and adjusts to protect stability. If you see a quality-lowered notice, that is the system saving your stream, not breaking it.

If you do drop, do not panic: viewers see the stream pause, and reconnecting quickly usually carries most of them through. A stream that stays dropped is auto-ended a few minutes later.
