The errors "Egress Aborted" with "End reason: StopEgress API" and "Start signal not received" occur when an egress is stopped before it can properly start, often because it is waiting for a start signal that never arrives or the source is unavailable. To resolve this issue, follow these steps: • Check Start Signal Configuration: If you are using Web Egress and have

await_start_signal

set to true, ensure your application sends the required start signal. If you do not need to wait for a signal, set

await_start_signal

to false. • Verify Source Availability: Make sure the room exists and has active participants, or that the target participant/track is present and publishing if using participant or track egress. • Timing Considerations: Avoid stopping the egress immediately after starting it. Allow enough time for the egress to initialize and receive necessary signals. • Monitor Egress Status: Use the ListEgress API to check that the egress is in the

EGRESS_ACTIVE

state before issuing a stop command. Do not stop egresses that are still in

EGRESS_STARTING

. • Review Request Configuration: Double-check your egress request for valid room names, participant identities, output configurations, encoding settings, and permissions. Addressing these points should resolve the issue with your egress process. If you need more specific troubleshooting, please provide details about your egress configuration and workflow.
