Introduction
This guide explains how to investigate and resolve streaming connectivity issues between encoders and origin servers in live video workflows. It is intended for broadcasters, streaming engineers, and infrastructure teams working with Cires21 live contribution and origin services.
Issue description
The issue was caused by connectivity problems between the encoders and the origin servers. As a result, the affected encoders were switched to backup streams while the problem was investigated and resolved with the infrastructure provider.
Signs
- Encoder output is not reaching the origin server.
- Live stream fails to start or drops unexpectedly.
- Backup stream is activated automatically or manually.
- Intermittent packet loss, timeouts, or connection resets are observed.
- Monitoring tools show instability between the encoder and origin path.
Basic troubleshooting steps
- Verify network connectivity between the encoder and the origin server.
- Check encoder status, stream configuration, and destination URL.
- Confirm that firewall rules, routing, and DNS resolution are correct.
- Review origin server health, availability, and ingest logs.
- Switch to a backup stream if available to maintain service continuity.
Advanced troubleshooting steps
Step 1: Validate the encoder-to-origin path
Test connectivity from the encoder network to the origin endpoint using the expected protocol and port. Check for latency, packet loss, or intermittent failures that may indicate an upstream network issue.
Step 2: Inspect encoder failover behavior
Confirm that the encoder is configured to move to the backup stream when the primary signal is lost. Verify that the failover logic is working as expected and that the backup source is valid.
Step 3: Coordinate with the infrastructure provider
Share timestamps, encoder logs, origin logs, and network observations with the infrastructure provider. Use this information to identify whether the issue is in the encoder environment, the network path, or the origin infrastructure.
Step 4: Restore service and monitor stability
Once connectivity is restored, return traffic to the primary stream if appropriate and monitor the session closely for recurring interruptions.
Prevention and best practices
- Stop recording when the signal is lost to avoid generating unusable content.
- Restart recording only after the signal returns and the stream is stable.
- Use monitoring and alerting to detect connectivity degradation early.
- Maintain backup streams and tested failover procedures for critical events.
- Document provider contacts and escalation paths for faster resolution.
Contact support
If the issue persists after completing the steps above, contact Cires21 support or your infrastructure provider with the relevant logs, timestamps, and stream details.

Conclusion
Connectivity issues between encoders and origin servers can usually be resolved by checking the network path, validating failover behavior, and coordinating quickly with the infrastructure provider. Using backup streams and pausing recording during signal loss helps reduce operational impact and prevents unusable recordings.
