Verifying the Connection

After clicking Start Streaming:

  1. The stream state in your dashboard will change from idle → connecting → live
  2. The HLS playback URL becomes active once the first segments are available (~5–10 seconds)
  3. If the state stays at connecting for more than 30 seconds, check your firewall — port 1935 TCP must be open outbound
