Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsIf your YouTube stream goes offline, first check whether the Docker container actually exited. A Docker restart policy can restart an exited container; it cannot repair a stream that has stopped publishing while its container remains up. Compare Docker’s state and timestamped logs with the error timestamps in YouTube Live Control Room before changing settings.
First determine whether the container exited
List running and stopped containers, then inspect the one running your encoder. Replace <container> with its name or ID.
docker ps -a
docker inspect -f 'status={{.State.Status}} exit={{.State.ExitCode}} restarts={{.RestartCount}} started={{.State.StartedAt}}' <container>Read recent application output with timestamps, then follow new output while reproducing the problem:
docker logs --timestamps --since 30m <container>
docker logs --follow --timestamps <container>- Container stopped or restart count increasing: investigate the process exit, exit code, startup errors, and host or Docker daemon lifecycle.
- Container remains Up while YouTube is offline: investigate the encoder’s publishing/reconnect behavior, YouTube ingestion errors, and the network path. A more aggressive restart policy alone may not help.
These commands rely on Docker’s available container logs. A configured logging driver may not support reading output with docker logs.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Choose a Docker restart policy for the intended lifecycle
Docker policies govern what happens after a container stops; they are not an application-level mechanism for reconnecting a still-running encoder to YouTube.
| Policy | Behavior |
|---|---|
no |
Default; do not automatically restart the container. |
on-failure[:max-retries] |
Restart after a nonzero exit. It does not restart the container just because the Docker daemon restarts. |
always |
Restart when the container stops, including after a daemon restart, subject to manual-stop behavior. |
unless-stopped |
Restart when the container stops, including after a daemon restart, but remain stopped after an operator manually stops it. |
For a long-running service that should return after an exit or daemon restart but stay down after an intentional manual stop, unless-stopped is a reasonable choice. In Docker Compose:

image: your-encoder-image
restart: unless-stoppedFor a container created with docker run, set --restart unless-stopped. To change an existing container:
docker update --restart unless-stopped <container>Docker applies restart policies only after a container has started successfully and run for at least 10 seconds. Docker documents an initial restart delay of 100 milliseconds, which doubles on subsequent attempts up to a one-minute maximum. A policy does not make an encoder reconnect if its process stays alive, nor does it correct an underlying ingestion or connectivity problem. Docker recommends restart policies for containers and advises against combining them with host-level process managers, which can conflict.

Check YouTube Live Control Room’s stream health
Open the stream in YouTube Live Control Room and inspect the Stream health indicator and its timestamped messages. YouTube’s dashboard checks the incoming stream; critical errors appear red and moderate errors yellow. Documented problem categories include incorrect bitrate, unsupported or incorrect codecs, audio/video stream structure, and keyframe frequency.
Compare YouTube’s error timestamps with Docker’s logs and state changes. A matching timestamp can help distinguish a process/container problem from an ingestion problem, but it does not by itself prove the cause. If Docker remains up while YouTube reports an ingestion error, focus on encoder configuration and the upload path rather than assuming a restart policy will fix it.

Verify encoder settings and the publishing connection
YouTube’s current encoder guidance lists RTMP or RTMPS ingestion, H.264, H.265, or AV1 video, AAC or MP3 audio, constant bitrate (CBR), and up to 60 frames per second. It recommends a two-second keyframe interval and says not to exceed four seconds. The appropriate bitrate depends on codec, resolution, and frame rate; use YouTube’s current settings table for the exact combination rather than applying one bitrate to every stream. YouTube recommends RTMPS for encrypted ingestion.
The encoder needs the stream URL and stream key shown in YouTube Live Control Room. Treat the stream key like a credential: do not expose it in public logs, screenshots, or support posts. If a third-party encoder reports a stream-key startup problem, YouTube’s troubleshooting guidance advises creating a new key in Live Control Room and updating the encoder.

Test before the next live event
YouTube recommends testing in advance with audio and movement similar to the planned stream, selecting a quality the upload connection can reliably sustain, and monitoring stream health during the event. Check the preview and audio/video quality, test encoder failover if you use it, and verify that any local archive is growing as expected. A setup that works briefly may still fail under the real event’s sustained upload demands, so watch both the encoder logs and YouTube’s health messages.
Account for Docker log storage
The default Docker json-file logging driver does not rotate logs by default, so a high-output container can consume substantial disk space. Docker’s local logging driver is designed for performance and disk use and includes rotation and compression. Logging-driver defaults or daemon changes apply to newly created containers; existing containers retain their logging configuration unless recreated with the new settings. A full disk is one possible operational concern, not an established explanation for a particular offline stream.
Or let it run in the cloud
If your goal is to keep uploaded video looping on YouTube without maintaining an encoder container at home, StreamNeo runs the stream in the cloud: upload a recording or build a playlist, add your YouTube stream key once, and go live. Nothing has to stay on at home; each slot streams the uploaded file as made, up to 4K 60fps, at one price per slot; and it automatically recovers if YouTube drops the stream. The first day is free with no card. Monthly billing is $9.99 per month. This is for uploaded videos and YouTube streams, not live camera input. Start your free day with StreamNeo.
