If OBS crashes, its automatic reconnect setting cannot reopen the application. You need one mechanism to relaunch the OBS process and a separate check that the restarted encoder can reconnect to the intended YouTube broadcast.
For an unattended fireplace stream, plan and test the full chain: the computer starts, a supervisor opens OBS, OBS loads the right profile and begins streaming, and YouTube still has a broadcast that can receive it. A successful OBS restart alone does not prove viewers are seeing the stream again.
First identify which part failed
“OBS is down” can describe several different problems. If the application has closed, the process has exited. If OBS remains open but reports a disconnected stream, the application is alive and its connection to the ingest service has failed. If OBS says it is streaming but viewers see a frozen or ended event, the problem may be downstream of the encoder or related to the broadcast lifecycle.
These distinctions matter because the controls address different failures. A process supervisor can detect that OBS has exited and launch it again. OBS automatic reconnect can retry a stream connection while OBS remains running. Neither action, by itself, proves that YouTube is accepting the restarted stream or showing it to viewers.
Start diagnosis with what you can observe. Check whether the OBS window or process still exists, whether its status shows a connection, and whether the YouTube Live Control Room shows incoming data and an active event. If OBS closed, note the time and check its logs or crash reports and the operating system's task history. If it remained open, investigate the connection and encoder status rather than treating a restart as the default fix.
A network failure can resemble an application failure from the viewer's side. OBS explains that dropped frames are associated with an unstable connection or a bitrate the connection cannot sustain, rather than necessarily indicating that OBS has crashed. Its stream connection troubleshooting guide discusses connection diagnostics; dynamic bitrate may reduce symptoms, but it does not repair a faulty route, an overloaded link, or interference from a VPN or firewall.
Configure the operating system to relaunch OBS
A supervisor is the part that watches for a process to exit and starts it again. It operates outside OBS, which is why it can address an OBS crash that OBS's own reconnect setting cannot. Configure it to launch the correct installation under the correct user account, and make sure its behaviour is predictable after both an application failure and a machine restart.
On Windows, Task Scheduler is one possible way to run OBS at sign-in or startup and to specify a response when a task fails. Microsoft's Task Scheduler documentation describes task settings, including restart behaviour. The exact task should reflect how your OBS setup uses the desktop session, devices, audio, and credentials; a task that starts successfully is not necessarily a task that can stream correctly.
OBS's launch guide says that automated launches should set the working directory to the folder containing obs64.exe when using scheduled tasks or similar automation. This avoids relying on a manual launch's current folder. Review the OBS launch parameters guide for the supported launch options and check the executable path on your own machine, since installation locations can differ.
A supervisor also needs sensible failure handling. If OBS crashes repeatedly because a scene, driver, plugin, or resource problem remains, immediately starting it over and over can create a loop rather than a recovery. Where the supervisor allows it, use a delay or restart limit, and arrange a way for a person to notice repeated failures. Confirm that only one OBS instance can be launched; multiple instances can compete for the same devices, settings, or stream key.
On Linux, systemd can supervise a service with restart policies such as Restart=on-failure, but OBS is a graphical application with session and device requirements. It may need a service wrapper and access to the appropriate display, audio devices, permissions, and logged-in user context. Do not assume a generic headless service unit will behave like OBS launched from your desktop. Validate the actual session and media path before leaving it unattended.
If the computer itself loses power, a process supervisor cannot act until the machine boots and the required session is available. Configure the computer's firmware and operating system to start as intended after power returns, then test that startup path. A UPS may bridge some power interruptions depending on its load and battery capacity, but it will not restart OBS after a software crash or resolve an internet outage.
If your stream has many scenes, filters, or changing media sources, simplify the workload before treating a hardware purchase as a recovery plan. OBS notes that demands vary with encoder, resolution, frame rate, and scene complexity. Its system requirements are not a guarantee that a particular setup can sustain a specific workload. For a simple static fireplace loop, compare the actual scene and encoding load with the more complex workflows discussed in choosing tools for YouTube live streaming rather than assuming a universal upgrade will prevent crashes.
Launch into streaming with --startstreaming
Once a supervisor can open OBS, decide whether the application should merely open or begin streaming automatically. OBS documents the --startstreaming launch parameter for starting a stream. That can remove the need for someone to press Start Streaming after a restart, but it is not a substitute for configuring the supervisor or verifying the destination event.
Before using it unattended, test the exact profile, scene collection, account, and stream destination that the task will load. An automated launch can faithfully start the wrong configuration. Keep a safe test broadcast or a controlled test window available, and confirm that the selected scene actually contains the intended fireplace video and audio rather than a blank canvas or an old test layout.
Use the launch guide's working-directory instruction as part of this setup, not as an optional detail. Then test a manual launch using the same executable, arguments, user account, and working directory the supervisor will use. Only after that works should you enable it as the automatic action after a process exit or boot.
Do not assume every restart should immediately begin broadcasting. If you need an operator to check a copyright notice, a content change, or a scheduled event before the stream resumes, automatic start may be the wrong choice. Keep the launch behaviour aligned with the channel's operating practice and with the way its YouTube event is prepared.
Make sure YouTube can receive the restarted encoder
OBS can relaunch and connect to a stream key, yet the viewer-facing broadcast may not recover as you expect. The destination has its own stream and broadcast lifecycle. A key may be wrong or changed, the relevant event may have ended, or the channel's workflow may require a manual Go Live action. Treat these as independent checks, not edge cases that an OBS restart automatically resolves.
YouTube's stream-key help describes managing stream keys and reusing stream settings. Confirm which key belongs to the channel and the intended stream, and make sure the OBS profile that starts automatically has that key selected. Avoid changing keys during an outage unless you can also update and test the configuration that the supervisor loads.
For scheduled broadcasts, understand the event's start and stop behaviour before relying on a restart. The OBS Project's YouTube streaming guide discusses scheduled streams and describes how auto-start and auto-stop settings affect reconnect scenarios. Labels and platform behaviour can change, so check the current controls in YouTube Live Control Room rather than relying on an old screenshot or a remembered setting.
The important test is viewer-facing: after OBS returns, does the intended YouTube event receive data and become visible again? A new encoder connection may not be useful if the prior event has ended or the wrong event is selected. Do not interpret an OBS status indicator as confirmation that YouTube has restored the broadcast.
If your channel uses a continuous loop with several sources or events, document which YouTube event and OBS configuration belong together. A process restart is not a good time to discover that a stream key, scheduled event, or scene collection was changed by someone else. The same operational discipline applies when you rotate playlists across several YouTube live channels: label configurations clearly and test the path each channel is meant to use.
Know what OBS automatic reconnect can and cannot do
OBS automatic reconnect is useful when OBS is still open and its streaming connection drops. The setting lets OBS retry connecting after a connection interruption. It is not a process supervisor, and it does not reopen OBS after the application exits. That is the central distinction for crash recovery.
You can configure reconnect behaviour in OBS's Advanced settings; consult the current OBS overview guide for where the control sits in the interface. Reconnect delay and retry behaviour should be tested against your network and platform workflow. A reconnect attempt that succeeds at the encoder level still needs the YouTube event to be available and to accept that incoming stream.
For a stable connection, reconnect settings may not come into play often. If you see repeated disconnects or dropped frames, first examine the connection path, bitrate, and whether other traffic is saturating the uplink. OBS's troubleshooting guidance cautions against treating a symptom setting as a root-cause fix. Changing network conditions, firewall rules, VPN routing, or output demands may be more relevant than shortening a retry interval.
It helps to think in layers. OBS automatic reconnect handles a connection retry while the process is alive. The operating-system supervisor handles the process exiting. The destination platform controls whether a broadcast remains available and can receive a returning encoder. Each layer can work while another fails, so do not describe the combined setup as guaranteed recovery.
For readers comparing a desktop-based workflow with another way to keep a fixed video on air, the practical trade-off is who has to maintain the local computer and recovery path. The OBS and Streamlabs comparison for 24/7 streaming can help frame that choice. When the local machine, scheduled task, and post-crash checks are the specific burden you want to remove, StreamNeo lets you upload the video and use your YouTube stream key to keep it broadcasting without leaving your own computer on.
Test the full chain, including power recovery
Do not wait for a real overnight failure to find out whether restart works. Run a planned test while someone can watch OBS and YouTube. Record the intended event, profile, scene, key, supervisor task, and the person who will verify the result. Begin with a controlled stop or test failure, then observe each stage rather than checking only whether the OBS window reappears.
A useful sequence is to stop streaming from OBS, verify what the event does in Live Control Room, then close OBS and let the supervisor launch it again. If your policy is to start automatically, observe whether --startstreaming is applied and whether the intended configuration is loaded. Confirm that YouTube receives the stream and that a viewer can see the restored fireplace scene. Repeat with a deliberate process failure only when it is safe to do so.
Next, test a connection interruption while OBS remains open. This distinguishes OBS's automatic reconnect path from the supervisor path. Note whether OBS remains alive, whether it retries, and whether YouTube keeps the event available. If these results differ from a full application restart, your recovery plan needs to state what action is expected for each case.
Test machine startup separately. Restart the computer under controlled conditions and verify that the right user session, network, audio path, OBS profile, and destination are present before assuming the live stream has resumed. If you need to understand behaviour after a power cut, simulate only what you can safely test; a normal reboot does not reproduce every outage condition. Any UPS should be assessed for the actual equipment load and runtime needs, not treated as an application-recovery tool.
Also test failure notification. A supervisor that retries in the background without alerting anyone can leave a stream broken for hours. Decide who checks the channel, how they learn that repeated restarts occurred, and what evidence they need: task history, OBS logs, the event status, and a viewer-side check. Keep a short runbook beside the machine so that a person can distinguish an OBS crash from a network or destination problem.
Monitor the recovered stream, not just OBS
After recovery, confirm the stream from the destination side. In YouTube Live Control Room, check for incoming video and audio, the expected event status, and any warnings. If practical, view the public stream from a separate device or network. The OBS preview can look correct even when the platform is not receiving data, and an encoder status alone does not tell you what a viewer can see.
Check for signs that the application recovered into the wrong state: a different scene, muted or missing audio, a frozen source, or a stream that starts but is not attached to the planned event. For a fireplace stream, a still image may be mistaken for a working loop. Verify that motion and audio behave as intended, and that the stream is not silently using an old file or test scene.
When a failure occurs, preserve useful evidence before changing several settings at once. Note the time, whether OBS stayed open, the supervisor's action, the YouTube event status, and any relevant log message. This makes the next diagnosis more precise and helps distinguish repeatable application crashes from intermittent network trouble.
A recovery process is only as useful as its human follow-up. Set a reasonable check routine for your channel and ensure someone can act if the supervisor reaches its retry limit or YouTube requires an operator. Do not promise yourself a particular recovery time or assume that an unattended stream is healthy simply because the computer has powered on.

FAQ
Can OBS restart itself after a crash?
OBS automatic reconnect does not relaunch a crashed process. Use an operating-system supervisor to start OBS again after it exits, and test that the supervisor launches the intended profile and session.
Will OBS reconnect to YouTube after a restart?
It may connect again if OBS starts with the correct stream settings and YouTube still has a broadcast that can receive the encoder. A restart does not guarantee that the event is still available or that it will resume for viewers, so check Live Control Room and the viewer-facing stream.
Does automatic reconnect fix dropped frames?
It can retry a connection after a disconnect while OBS remains open, but it does not repair the underlying network problem. OBS associates dropped frames with connection instability or a bitrate the connection cannot sustain; investigate the route and output demands as well.
What should I test before leaving a fireplace stream unattended?
Test an OBS process exit, a connection loss with OBS still running, and a machine restart as separate cases. For each, confirm the supervisor or reconnect behaviour, the selected scene and key, YouTube's event status, and what a viewer sees.
