OBS WebSocket lets a compatible client remotely control OBS scenes and sources; it does not send your video to YouTube. YouTube’s stream URL and stream key belong in your encoder’s streaming settings, while the WebSocket connection uses OBS’s host, port and its own password.
For a loop stream, that distinction matters: remote control can help you change or monitor OBS, but it cannot repair an unstable ingest connection or make an unattended broadcast reliable by itself. Set up the control connection with authentication, keep it within a trusted network, and test control and delivery as separate parts of the workflow.
What OBS WebSocket controls
OBS WebSocket is an interface for external software to communicate with OBS Studio. A compatible client can request changes to scenes and sources, which is useful if you want to operate a stream from another device or automate a repeated action without sitting at the streaming computer. OBS describes it as a way to automate or control scenes and sources with external tools in its Remote Control Guide.
That is the control layer, not the broadcast path. It does not carry your video or audio to YouTube, and its password is not the credential YouTube uses to accept an encoder feed. If a remote-control app cannot connect, investigate the OBS WebSocket settings and network access. If YouTube reports that it is not receiving a stream, investigate OBS’s streaming configuration and connection instead.
The distinction is practical when a channel runs a prerecorded video on repeat. Your OBS scene and media source determine what OBS presents; the WebSocket client can control OBS elements that it supports. YouTube receives the encoded output through the separate streaming connection. For the broader job of selecting software for a continuous prerecorded broadcast, see this guide to software for streaming prerecorded videos on YouTube 24/7.
Do not assume that connecting WebSocket sets up a loop. The OBS pages cited here describe remote scene and source control, not a definitive loop or playlist recipe. Configure the media source or playlist behaviour for your own project, then test it in OBS before depending on it for a long run.
Check OBS version and WebSocket availability
OBS WebSocket is included by default in OBS Studio 28 and newer. If you are using an older release, availability may depend on installing the separate plugin; update OBS where practical and check the official OBS remote-control documentation before adding components.
Start by checking the version shown in OBS, then look for the WebSocket settings in the Tools menu. If the item is missing, do not assume that the YouTube account or stream key is responsible. The installed OBS version is the first thing to check. Older installations may need the plugin, while a current installation should include the feature.
Updating can affect an established stream setup, so avoid making a version change immediately before relying on unattended operation. Note your current configuration, use the official download and documentation, and test your scene, audio, and output after updating. The key point is that availability is tied to OBS software and its WebSocket component, not to whether a YouTube live event is scheduled.
OBS lists compatible clients such as Streamer.bot, Macro Deck, Touch Portal and OBS Blade in its remote-control guide. These are examples, not a requirement or an endorsement of commercial terms. Choose a client that fits the actions you need, and verify its documentation and permissions before supplying it with access to OBS.
Open Tools → obs-websocket Settings
In OBS Studio, open Tools → obs-websocket Settings. The wording may appear with slightly different capitalisation depending on the version, but look for the obs-websocket entry under Tools. The settings dialog is where you enable the server, choose its port and configure authentication.
First confirm that the WebSocket server is enabled. If it is off, an external client has nothing to connect to, even if you have copied the right host and port. Then note the port shown in the dialog rather than relying on a remembered value: it may have been changed from its default.
Keep the OBS window and the client’s connection form available while setting this up. The client typically needs the computer or host running OBS, the configured port, and the WebSocket password if authentication is enabled. Enter those values only in the intended client. Do not paste the YouTube stream key into a WebSocket password field, or the WebSocket password into YouTube’s stream key field.
A clean setup is easier to troubleshoot when you change one layer at a time. First confirm that OBS itself is open and the server enabled. Next attempt a connection from the chosen client on a trusted network. After remote control works, test the separate YouTube broadcast path in OBS and YouTube Studio.
Enable authentication and set a password
Enable authentication in the WebSocket settings and set a strong, unique password. OBS recommends password protection because a client with access can control OBS; treat this password as an administrative credential, not as a casual convenience. A remote-control connection should never be left unauthenticated for ease of testing.
Choose a password that is not used for YouTube, email, or another account. Store it in a password manager or another secure place you can reach when configuring a trusted client. If you later rotate the password, update the client too; a mismatch will prevent the client from authenticating even if the host and port are correct.
Limit who and what can reach the WebSocket server. Prefer a trusted local network and configure the client on a device you control. The reviewed OBS guidance does not prescribe one universal network design for remote access, so do not expose the OBS port publicly as a shortcut. If you need access away from the local network, use a secure approach you understand and can maintain rather than opening a port broadly.
Authentication is not a substitute for deciding whether a client deserves control. A client may be able to switch scenes or alter sources, which could interrupt the output you intended to keep live. Review the client’s capabilities and permissions, and avoid entering credentials into untrusted software. When no longer needed, disable the WebSocket server or remove access through the security controls available in your setup.
Understand the default port and connection details
OBS WebSocket 5.x uses port 4455 by default, and the port can be changed in settings. The obs-websocket project documentation explains the version and connection details. A client must use the configured endpoint and matching authentication details; if you changed the port, entering the default will not work.
| Connection detail | What to enter or check | What it is not |
|---|---|---|
| Host | The computer or reachable host running OBS | Your YouTube channel name |
| Port | The value shown in obs-websocket Settings; 5.x defaults to 4455 | A YouTube ingest port to guess |
| Password | The WebSocket authentication password, if enabled | Your YouTube stream key |
| Stream URL and key | The separate encoder details from YouTube | OBS WebSocket connection details |
A failed connection can come from a simple mismatch: OBS is not running, the WebSocket server is disabled, the host cannot be reached from the client, the port differs, or the password is wrong. Check each item deliberately rather than repeatedly changing credentials. If the client offers a connection test or clear error message, use it to narrow down which layer is failing.
The port number alone does not make remote access safe. A configured port is only one part of an endpoint, and network reachability determines whether the client can contact it. Keep that access limited to trusted devices and networks; do not publish connection details or include passwords in screenshots, public support posts, or shared setup notes.
Keep YouTube URL and stream key separate
YouTube’s stream URL and stream key are encoder credentials, used to send a feed into YouTube. Configure them separately in OBS’s streaming settings or choose YouTube as the service if that workflow is offered. YouTube explains its encoder setup in Create a YouTube live stream with an encoder, and stream details in Manage live stream settings.
Depending on whether you are using an instant or scheduled stream, the steps in YouTube Studio can differ. Select or create the appropriate live stream, copy the stream URL and key from the relevant YouTube workflow, and enter them in the encoder configuration. Then start sending the feed from OBS. Some workflows also require a manual Go live action in Live Control Room; follow the current instructions shown for your stream rather than assuming that starting OBS always publishes the event.
Keep the stream key private. YouTube treats it as a credential for the encoder feed, not a substitute for the OBS WebSocket password. If you think it has been exposed, use YouTube’s current Live Control Room controls to reset it, then update OBS with the replacement. Rotating the key will not fix a WebSocket connection, and rotating the WebSocket password will not replace the YouTube key.
This separation also helps with troubleshooting. If the remote client can change an OBS scene but YouTube does not receive video, the control connection is working while the ingest path still needs attention. If YouTube receives the stream but the remote client cannot connect, do not alter the stream key; check the WebSocket server, endpoint and authentication.
For a playlist-based OBS channel, WebSocket is one part of operating the scene, not the whole stream workflow. This guide to streaming a playlist of lectures 24/7 on YouTube with OBS covers the broader OBS playlist context. If OBS output stutters, compare that issue with the separate checks in how to stop OBS videos from stuttering in a 24/7 YouTube stream; a remote-control password will not address dropped frames.
Connect and test remote control securely
Once OBS is enabled and authenticated, configure a compatible client with the host, configured port and WebSocket password. Start on a trusted network, with OBS visible, and try a low-risk action such as switching between test scenes. Confirm that OBS reflects the action and that the client reports a connection, then disconnect and confirm that your planned OBS output is still configured as expected.
Before relying on a continuous channel, rehearse the whole sequence. Verify the scene and media source, confirm the encoder settings, start the feed, and check the live status in YouTube Studio. Test the remote actions you expect to use, including what happens if the client closes or reconnects. Do not treat a successful client connection as proof that YouTube is receiving a healthy stream.
WebSocket settings do not ensure uninterrupted delivery. OBS notes that dropped frames and disconnections can result from an unstable connection or a connection that cannot sustain the selected bitrate. Its Stream Connection Troubleshooting guidance addresses that broadcast path; investigate network conditions, server selection and bitrate separately from WebSocket access.
A useful fault-finding order is to ask where the failure appears. If control fails, confirm OBS is open, the server enabled, the endpoint correct and authentication matched. If delivery fails, inspect OBS’s stream status and YouTube’s Live Control Room, then work through the official connection troubleshooting guidance. If the video itself stops looping while the connection remains live, inspect the OBS media or playlist configuration rather than changing credentials.
For channels that must run when the operator’s computer is off, remote control alone does not solve the operating requirement. StreamNeo addresses the specific need to keep a file-based broadcast running without leaving your own computer on: upload the video once, connect your YouTube stream key, and the broadcast continues from the cloud with monitoring and automatic restart if it drops. It is YouTube-only, and the YouTube credentials remain distinct from OBS WebSocket control.

FAQ
Is OBS WebSocket the same as my YouTube stream key?
No. OBS WebSocket authenticates a client that controls OBS, while the stream URL and key let OBS send the encoder feed to YouTube. Keep the two credentials separate and never use the stream key as the WebSocket password.
Where are OBS WebSocket settings?
In OBS Studio, open Tools → obs-websocket Settings. There you can enable the server, check the configured port and enable authentication. If the option is missing, check your OBS version and whether the older plugin is required.
What port does OBS WebSocket use?
OBS WebSocket 5.x uses 4455 by default, but the setting can be changed. Use the port shown in OBS and enter the same value in the client, along with the correct host and password.
Will WebSocket keep a YouTube loop stream online?
No. It gives a compatible client remote control over OBS, not a more reliable connection to YouTube. Test delivery separately and troubleshoot network or bitrate problems using OBS’s connection guidance.
