1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesYou can keep a YouTube stream running from Hetzner Cloud by creating a VPS, sending an encoded feed from it to YouTube Live, and supervising the encoder so it can recover after a process or server restart. The VPS is only the machine: you still need to configure the media source, encoder, YouTube stream key, network access, and monitoring. This guide uses Ubuntu and FFmpeg as an example approach; the exact command and server size depend on your media and encoding workload.
What you need before starting
- A YouTube channel eligible to livestream. YouTube currently requires channel verification, no live-streaming restrictions in the previous 90 days, and that the streamer be at least 16. Check the account-specific requirements in YouTube’s live-streaming eligibility guidance.
- A video or other media source available to the server, and an encoder such as FFmpeg that can read it and send a live feed.
- A Hetzner Cloud account, a server with public networking, and an SSH key for administration.
- A stable outbound network path whose capacity exceeds the full stream bitrate. YouTube recommends reserving 20% headroom above the total bitrate.
A stream that is merely running on a VPS is not guaranteed to remain continuously available. Failures can occur in the server, network, encoder, source file, or YouTube ingest path; supervision, alerting, and regular checks are part of operating it.

Prepare YouTube Live and protect the stream key
- In YouTube Studio, select Create → Go Live, then create or select a stream in Live Control Room.
- Copy the server URL and stream key shown for the selected stream. The encoder needs both. Treat the key like a password: do not place it in public code, screenshots, or shell history. If it is exposed, reset it in Live Control Room and update the encoder with the replacement.
- Choose the ingest protocol and settings in line with YouTube’s current encoder guidance. YouTube recommends RTMPS. Its guidance recommends CBR, a two-second keyframe interval (not more than four seconds), and lists H.264, H.265/HEVC, and AV1 among supported codecs. Consult the current YouTube encoder settings and bitrate table for the resolution and frame rate you intend to send.
Do not assume a server URL or stream key from one event applies to every stream; use the values shown for the stream you have configured.
Create and secure the Hetzner Cloud server
Choose an operating system and location
- In Hetzner Console, create a server and select its type, location, OS image, networking, and SSH key. Hetzner offers Ubuntu among its Cloud OS choices. Include the SSH key during creation where possible: Hetzner’s creation guide says adding one later through the Console is not available, although other tooling may add one.
- Choose a location based on your operational needs and network path. Hetzner’s documentation recommends closer locations for larger projects, but does not identify a best location for YouTube ingest specifically.
- Select a server type based on the actual workload. Sending an already encoded video can use much less CPU than real-time transcoding. There is no universally sufficient plan established for this task; monitor CPU, memory, network, and storage use, then resize or change the approach if the workload requires it.
Hetzner’s Cloud server overview describes server options, but its documentation does not provide a stream-specific benchmark. For a more predictable workload, consider whether shared or dedicated resources suit your needs; neither is automatically the right choice for every feed.

Connect over SSH and limit inbound access
- Use an SSH client to connect to the server’s public IP address with the private key corresponding to the key selected at creation. Keep the private key secure and restrict access to the server to administrators who need it.
- If you use a Hetzner Cloud Firewall, review its rules before attaching it. Hetzner documents that inbound traffic is blocked by default unless allowed, while outbound traffic is permitted by default unless outbound rules are configured.
- Allow only the inbound administration access you need, such as SSH from trusted addresses where practical, and retain the outbound connectivity required by the encoder. YouTube receives the feed as an outbound connection from the VPS; do not open inbound media ports simply for YouTube ingest.
Do not pin a presumed YouTube destination IP or open a guessed port range. Ingest endpoints and network requirements should be taken from current YouTube and encoder configuration, not assumed to be fixed.
Configure the encoder and media source
Decide whether to pass through or transcode
If the source is already encoded in a format and bitrate suitable for YouTube, sending it without re-encoding can reduce CPU use. If it does not meet the intended ingest settings, the encoder may need to transcode it, which increases CPU demand and can affect the server size required. The right choice depends on source format, target resolution and frame rate, and the encoder implementation.

Install and configure an encoder
Install FFmpeg or another encoder capable of reading your source and publishing to the YouTube server URL using the stream key. Store credentials in a protected configuration or environment mechanism rather than embedding a real key in a public command example. Confirm that your chosen encoder supports the selected protocol and codecs.
Recommended Free Tools
This guide does not prescribe a universal FFmpeg command: looping behavior, timestamp handling, reconnect behavior, and error handling vary with the source and FFmpeg options. Validate a command against the current FFmpeg documentation and test it with your actual file before relying on it. A loop option alone does not establish that the process will reconnect forever after an ingest failure.

Match YouTube’s ingest requirements
- Use RTMPS when supported by your encoder and the stream configuration.
- Set constant bitrate (CBR) where appropriate, and configure a two-second keyframe interval without exceeding four seconds.
- Choose a codec, resolution, frame rate, and bitrate using YouTube’s current table for the intended output. Higher resolution and frame rate require more upload capacity; transcoding them also requires more server resources.
- Ensure the source includes the audio and motion characteristics your viewers should receive. A technically connected feed can still have silent audio, frozen video, or an incorrect aspect ratio.
YouTube transcodes incoming live video for playback variants, but that does not make an unstable or noncompliant encoder feed reliable. The feed you send still needs to be valid and consistent.
Test the feed before relying on it
- Start the encoder and check the Live Control Room preview before making the stream public or depending on it for a production event.
- Verify picture, motion, audio, aspect ratio, and the watch page. Check Live Control Room stream-health messages and address any warnings before unattended operation.
- Measure the server’s available upload capacity under realistic conditions. YouTube recommends bandwidth exceeding the total stream bitrate by 20%; if you send primary and backup feeds, include both in the bandwidth budget.
- Leave the test running long enough to observe resource use, source looping, and whether timestamps or audio drift become a problem.
Keep it running and detect failures
Use process supervision
Configure a process supervisor so the encoder can start on boot and restart after a crash. A system service manager such as systemd is one possible choice; its unit, restart policy, and configuration are operator decisions, not requirements specified by YouTube or Hetzner. Make sure the restart behavior does not create a tight failure loop if the source file is missing or credentials are invalid.

Monitor the whole path
Monitor at least the encoder process, CPU and memory use, disk space, network availability, and YouTube stream health. Add alerts that reach someone able to respond. A process supervisor can restart a crashed encoder, but cannot fix a deleted source, exhausted disk, expired or reset key, server outage, blocked outbound route, or YouTube-side problem.

Choose between a continuous event and shorter scheduled streams
YouTube says streams under 12 hours are automatically archived. That guidance does not establish archive behavior for an indefinitely running event. If preserving replays matters, check YouTube’s current event and archive guidance before deciding whether to split a continuous feed into scheduled shorter events or preserve a separate local recording. Do not assume a 24/7 event will produce an unlimited or complete replay.
Costs and practical trade-offs
Budget for the Hetzner server type, public networking, storage for media, and any additional resources your encoder needs. Hetzner says server prices vary by type, and public IPs are a separate consideration. Its overview lists Primary IPv4 at €0.50 per month excluding VAT, but that figure is from documentation last changed 2022-06-28 and should not be treated as a guaranteed current charge; verify live pricing before provisioning.
Real-time transcoding may require a larger server than sending an already encoded source, while a more capable server does not resolve source-file, network, or YouTube ingest failures. Compare the complete recurring hosting cost with the workload you actually need, then monitor resource use rather than choosing a plan from resolution alone.
Common problems and fixes
YouTube does not receive the stream
- Confirm the server URL and stream key match the stream selected in Live Control Room.
- Check that the key has not been reset, copied with extra characters, or exposed and replaced.
- Verify that the encoder supports the configured protocol and that outbound network access is allowed by server and firewall rules.
- Use the Live Control Room health status and encoder logs to distinguish an authentication problem from a network or format problem.
The feed connects but YouTube reports poor stream health
- Check that bitrate and resolution match YouTube’s current table and that the network has the recommended headroom.
- Verify CBR and keyframe interval settings, then check CPU usage if the server is transcoding.
- Inspect source playback for intermittent stalls, timestamp issues, missing audio, or a file that does not loop as expected.
The encoder stops and stays stopped
- Check process logs for invalid input, missing files, permissions, key errors, or resource exhaustion.
- Confirm the process supervisor is enabled for startup and configured to restart on failure.
- Check free disk space and whether the server rebooted or lost network access; resolve the underlying fault before restarting repeatedly.
The stream is live but the archive is missing or incomplete
Do not infer archive behavior for a long-running event from YouTube’s automatic-archive guidance for streams under 12 hours. Review the current archive guidance and use shorter scheduled events or a separate recording strategy if replay preservation is essential.
