A YouTube stream stopping after a few hours does not, by itself, show that Hetzner caused the failure. Match the encoder log, YouTube Live Control Room status and messages, and VPS metrics at the exact time the stream stopped. That evidence helps distinguish a stopped encoder process from a connection or bitrate problem, a YouTube ingest error, or a host or network interruption.
First, identify what actually stopped
Write down the time the public stream stopped, preferably in UTC. Then compare what YouTube showed with what the encoder and VPS were doing at that same moment. A stream marked ended, offline, or waiting for encoder input can point to different failure layers; the status alone is not a complete diagnosis.
- Encoder process exited or restarted: inspect its logs and the service or process manager around the failure time. Compare with CPU, memory, disk, and network metrics.
- Encoder stayed active but reported dropped frames or disconnection: investigate the connection to YouTube’s ingest server, packet loss or interruptions, and whether the bitrate is sustainable.
- YouTube reported an encoder or stream-key error: verify the ingest URL and the current stream key in Live Control Room, then check the encoder configuration.
- VPS or network interruption is suspected: compare Hetzner Status and the VM’s metrics with the failure timestamp. A correlation is evidence to investigate, not proof of responsibility.
Keep the encoder logs and local recording before changing settings. YouTube recommends monitoring stream health and checking local archive integrity; preserving both makes it easier to compare the failure with the stream’s last good output.
Work through the failure in order
- Record YouTube’s state and the exact stop time. In Live Control Room, note whether the stream is marked ended, offline, or waiting for encoder input, and save any stream-health messages.
- Check whether the encoder process is still running. Use the logs and your process or service manager to determine whether it exited, restarted, reported an encoder error, or continued sending. If it exited, examine the service and process logs at that time along with CPU, memory, disk, and network metrics.
- Compare the encoder’s output with YouTube’s health information. Check whether the local recording continued to grow and whether the archive is intact. A local recording can help establish whether the encoder was still producing content even if the public stream stopped.
- If frames dropped, investigate the connection and bitrate. OBS says dropped frames or intermittent disconnections indicate a network issue between the computer and the remote ingest server; excessive drops can disconnect the stream. Compare the configured bitrate with sustained upload capacity, and look for packet loss or connection interruptions. YouTube advises choosing a quality the connection can reliably support, testing the setup before relying on it, and monitoring health during the stream.
- Check the stream settings against YouTube’s guidance. Use CBR, set the keyframe interval to the recommended two seconds (and no more than four seconds), and use RTMPS for encrypted ingestion. Test the exact setup before depending on it for a long stream.
- Investigate key or ingest errors only when the evidence points there. Confirm the ingest URL and current stream key in Live Control Room and ensure the encoder uses them. YouTube recommends getting a new key and updating the encoder for certain encoder start errors; rotating a key is not an established universal fix for a stream that ran successfully for hours before stopping.
- Check for a provider-side correlation. Review Hetzner Status for an incident at the failure time and compare it with host and network metrics. Hetzner’s Cloud and vServer service agreement describes availability terms and exclusions, but an SLA figure does not establish that Hetzner caused a particular stream failure.
- Change one thing at a time. Preserve the original logs and recording, make a targeted change based on the evidence, then test the same stream configuration. Changing several settings at once makes it harder to tell which change addressed the problem.
How to interpret the evidence
| What you observe | Most relevant checks | What it does not prove |
|---|---|---|
| The encoder process stopped or restarted | Encoder and service logs; CPU, memory, disk, and network metrics at the timestamp | It does not, on its own, establish whether software, configuration, or the VPS caused the process to stop. |
| The encoder stayed active but dropped frames or disconnected | Configured bitrate versus sustained upload capacity; connection interruptions and packet loss; YouTube stream health | Dropped frames do not by themselves identify Hetzner as the source of the network problem. |
| YouTube reported an encoder or key error | Live Control Room messages; ingest URL and current stream key; encoder settings | A key rotation is not a general remedy for every stream that stops after running successfully. |
| A host or network incident is suspected | Hetzner Status and VM or network metrics, correlated to the same time | The service agreement’s availability terms do not prove provider fault in an individual case. |
Do not confuse a missing archive with a stream that stopped
YouTube says streams longer than 12 hours may not be captured as archives; streams under 12 hours can be automatically archived. That is an archive-capture limitation, not a stated rule that YouTube automatically stops a live stream at 12 hours. It does not explain a stream ending after only a few hours. Check Live Control Room and encoder logs to determine whether the live broadcast ended or only the saved archive is missing.

What Hetzner’s availability terms do—and do not—tell you
Hetzner’s current Cloud and vServer Service Agreement, accessed October 3, 2026, states a 99.9% monthly availability commitment, expressed as “commercially reasonable efforts” for Cloud Servers. Its availability definition and exclusions include failures attributable to customer-introduced software or configuration and certain network interruptions beyond Hetzner’s control. This is not a guarantee that an individual YouTube stream will stay connected, nor is it evidence that a particular failure originated at Hetzner. Use the agreement alongside timestamped status information and VM metrics, rather than as a substitute for diagnosing the encoder and ingest path.
