Before you start: make sure the channel can stream
YouTube requires a verified channel with no live-streaming restrictions in the past 90 days. Streamers must be at least 16 years old. Enabling live streaming for the first time may take up to 24 hours, so do not wait until just before an event to activate it.

Save or apply the settings, then start the encoder from Streamlabs Desktop. Starting the encoder sends your feed to YouTube; it does not necessarily make a scheduled or manually controlled stream public.
-
Return to YouTube Live Control Room and check that the preview receives your video and audio. When the preview and stream status are ready, use YouTube’s Go live control if the stream requires a manual start.

Check the preview and stream-health messages before and during the event; an encoder showing “live” does not by itself confirm that viewers can see the intended feed.
Troubleshooting a key or connection error
Streamlabs does not connect or YouTube reports a start error
Retrieve the key again from the selected stream’s settings and paste it into Streamlabs. YouTube specifically recommends refreshing the key in the encoder when a third-party encoder fails to start. Also confirm that the server URL and key have not been swapped. YouTube Help: Fix live stream errors
The key appears right, but no feed appears in the preview
Verify that you selected the intended stream in Live Control Room, that live streaming is enabled for the channel, and that Streamlabs is using the matching server URL and key. Then check the encoder’s connection status and YouTube’s stream-health messages.

You suspect someone else has your key
A channel owner or manager can reset the key in Live Control Room. After resetting it, replace the old value in Streamlabs with the new key; the encoder cannot keep using the revoked one. YouTube Help: Manage your stream settings
Or let it run in the cloud
If your goal is a YouTube channel that plays uploaded videos continuously, StreamNeo is a different approach from sending a live encoder feed from Streamlabs: upload a recording or build a playlist, add your YouTube stream key once, and go live. It loops uploaded videos from the cloud, so nothing has to stay on at home. StreamNeo streams the upload as made, up to 4K 60fps, at one flat price per slot; it automatically recovers if YouTube drops the stream. The first day is free with no card. Monthly pricing is $9.99 per month. See StreamNeo or start your free first day.
