Selecting an incorrect or poor-performing ingest server can prevent your stream from going live, even if your software says it's running.

If your bitrate is set too high (e.g., above 6,000–8,000 Kbps), Twitch may reject your feed, causing it to display as offline.

Use the Twitch Inspector tool to check for quality issues (aim for 100% quality).

Instead of "Automatic" in your streaming software, choose a specific, close-by ingest server, as described in the Twitch help documentation. To help you fix this, could you tell me:

Always use a wired connection for streaming instead of WiFi for a more stable broadcast.
