A Larix stream that keeps disconnecting can fail at several points: the app may lose its publishing connection, YouTube may reject the connection details, the phone may struggle to encode, or the outbound network may falter. Start by identifying which link is failing, then change one thing at a time and check a test stream in YouTube Live Control Room.
A reconnect setting can change how Larix retries, but it cannot make a weak uplink reliable or guarantee that a dropped stream will return. The checks below are ordered to separate configuration, device, network and ingest problems before you adjust retry behaviour.
First locate where the connection breaks
Use a short private or unlisted test and watch both Larix and YouTube Live Control Room while it runs. Note the time of any interruption and what each side reports. This simple record is more useful than changing several settings and then guessing which one mattered.
There are three distinct symptoms to separate. Larix may report that publishing disconnected or is reconnecting; YouTube may show that the incoming feed or stream health has a problem; or both may look healthy while viewers report playback stopping. The last case may involve playback or a viewer’s connection rather than the connection from Larix to YouTube.
If Larix reports a publishing drop, begin with its connection configuration, app state and network path. If Larix still appears to publish but Live Control Room reports an ingest or encoder issue, inspect the incoming feed, credentials and encoder output. If the control room shows a healthy incoming stream while viewers cannot watch, do not immediately alter Larix: first confirm the report from another viewer or device.
YouTube’s troubleshooting guidance separates encoder output from the outbound connection. Check whether the encoder is producing a usable stream, then test the connection carrying it to YouTube. The YouTube RTMP server URL walkthrough can help you locate the destination information before checking Larix.
Write down the phone model, operating system, Larix version, connection type, time and any exact error message. Do not include your stream key in notes you share publicly. The title of this problem alone cannot reveal whether the cause is a particular phone, network or app version; the observations from your test should decide the next branch.
Verify YouTube’s ingest URL and stream key
Larix needs the correct YouTube ingest server URL and the matching stream key. In Live Control Room, open the stream’s settings and copy the current server URL and key into the connection profile in Larix. Softvelum describes the connection as the server URL combined with the stream name or key, so check both parts rather than assuming a saved profile is still current.
Compare the values carefully. A profile can point to an old destination, or a key may have been changed in YouTube while Larix still holds the previous one. If YouTube cannot start a stream from a third-party encoder, its guidance includes obtaining a new stream key and updating the encoder. Follow the current instructions in YouTube’s live encoder troubleshooting guide; do not reset a key without a reason, since other encoders using that key may then need updating too.
Never paste the key into a support forum, public screenshot, video description or message to someone who does not need it. Treat it like a password for sending video to your channel. If you have shared it accidentally, replace it in Live Control Room and update the Larix profile that should publish.
Check that the selected protocol and destination agree. YouTube recommends RTMPS for encrypted ingestion, but that is not proof that changing protocol will resolve a disconnect. Confirm that the URL you copied is the one intended for the chosen protocol and that the Larix profile supports it. Avoid changing the URL, key and encoder settings simultaneously, because a successful test would not show which change helped.
After correcting a profile, make a short test and observe whether Larix establishes publishing and whether Live Control Room receives the stream. If the same drop persists with the correct current credentials, move on rather than repeatedly regenerating keys.
Inspect Larix, the phone and encoder output
Check for an available Larix update and note the version installed before testing again. Menus and options can differ between app versions and operating systems. Softvelum’s Larix documentation is the appropriate reference for the current app behaviour; if a menu label does not match, do not assume a similarly named control has the same effect.
Look at the local preview before focusing on YouTube. Confirm that the intended picture and audio are present and that they do not freeze or break up on the phone itself. A poor local feed or an app that becomes unresponsive points towards device or encoder conditions, even if the network is also imperfect.
Check whether the phone is under unusual load, overheating, running low on battery or switching between foreground and background activity. Close unnecessary heavy apps for the test, keep the phone powered appropriately, and avoid locking or moving the app out of its normal operating state until you know how that platform handles background publishing. These are diagnostic steps, not a promise that a phone can encode continuously in every environment.
If the feed is unstable locally, simplify the video configuration for a test. YouTube publishes recommended bitrate ranges that vary by codec, resolution and frame rate; for example, its guidance includes different recommendations for 720p at 30 frames per second depending on codec. Treat that table as guidance for encoding, not as evidence that a given mobile uplink can sustain the chosen rate. Check YouTube’s encoder settings recommendations and choose a profile the device and connection can both support.
A simpler test profile can help isolate load: reduce resolution or bitrate, keep the content and network the same, and see whether the local preview and incoming feed become more stable. If local video and audio are sound but YouTube still loses the connection, the outbound path becomes a stronger suspect. If only playback drops after YouTube reports a healthy incoming feed, return to the viewer-side symptom instead of lowering encoder quality without evidence.
Test the actual outbound upload path
Download speed does not tell you whether the phone can continuously send a live stream. Run an upload test on the same phone and network, in the place and time you expect to broadcast. A result from another room, another device or a quiet part of the day may not represent the conditions during the stream.
Compare available upload capacity with the stream’s total bitrate and other traffic using the connection. YouTube recommends leaving 20% headroom above the stream bitrate. That is a recommendation, not a guarantee: mobile and shared connections can vary, and a brief drop can still interrupt publishing. YouTube’s reliable network guidance notes that a connectivity disruption can break a stream.
For instance, if a household connection is being used for a live broadcast while another device uploads large files, the speed test taken earlier may overstate what is available to Larix. Pause competing uploads for a controlled test. If the stream steadies, the issue may be contention; if it does not, test a more stable connection at the same location before changing several encoder variables.
Compare options by observed stability, not by whether a connection is called Wi-Fi or mobile data. Wi-Fi may be steady in one room and weak in another; a mobile signal may be strong at one time and variable later. Test the actual route that you plan to use. Where upload fluctuates, try a different stable network if available, or lower stream bitrate and resolution to a level that leaves the recommended margin, then repeat the test.
A 24/7 music stream setup guide discusses planning a continuous channel, but a phone-based Larix broadcast has its own device and network constraints. A configuration suitable for a short mobile test should not be assumed suitable for an unattended all-day channel.
Adjust Larix reconnect behaviour where available
Only tune retry behaviour after checking the URL and key, local encoder output and uplink. Reconnect settings can affect what the app does after a lost connection; they do not repair the cause of repeated losses. Do not expect an uninterrupted broadcast or automatic recovery in every situation.
Softvelum’s FAQ places Advanced settings under Settings > Connections and describes a Reconnect timeout: the wait before Larix attempts to connect again. It also documents a “Don’t check network presence” setting that affects attempts when the network is unavailable or briefly goes offline. These labels and controls may vary with app version and platform, so confirm them in the relevant Softvelum FAQ rather than looking for every option on every device.
The FAQ also describes iOS-specific reconnect timeout without network, idle timeout and an unsent-data threshold. These are not universal controls. If your version exposes a reconnect timeout, understand what waiting interval it changes before adjusting it; if your version does not show an option, do not infer that another platform must have it. Change one available setting at a time and record the original value so you can revert.
A useful test is to observe what happens during a controlled, brief network interruption, but do not use a public broadcast as the experiment. See whether Larix retries, how Live Control Room reports the gap, and whether the connection returns when service is restored. A retry may help after a transient interruption, but a persistently weak uplink, incorrect credentials or overloaded device still needs a different remedy.
Run a test and read YouTube stream health
After a change, repeat the same short private or unlisted test. Keep the location, device, content and network as consistent as practical. If you lower the bitrate, update a key or change a retry option all at once, you will not know which adjustment affected the result.
Watch Larix and Live Control Room together. Record whether Larix says it is publishing, whether YouTube receives an incoming bitrate, and which stream-health message appears around a drop. A healthy local preview plus a disappearing incoming feed points you back towards the outbound connection or publishing configuration; local glitches point towards device or encoder conditions. Use the message as evidence, not as a diagnosis by itself.
If YouTube continues to report an encoder error while Larix remains connected, revisit the encoder profile and current YouTube recommendations. If incoming bitrate falls as Larix reports reconnecting, investigate the network route and capacity. If Live Control Room stays healthy while viewers report a problem, compare playback from another connection before changing the sending configuration.
Keep a brief change log: time, network, profile, observed Larix status, Live Control Room status and the one adjustment made. It helps distinguish an improvement from a coincidental lull in network traffic. For long-running channel planning, a guide to logging stream status during a 24/7 broadcast covers a related monitoring workflow, though its OBS-specific steps do not apply directly to Larix.
If a phone, local network and app need to remain powered and attended for a continuous channel, be realistic about that operating burden. StreamNeo removes the specific need to keep your own computer switched on for a file-based 24/7 YouTube stream; it does not diagnose or repair a Larix mobile publishing connection. Consider it only if your actual requirement is a continuous uploaded-video channel rather than a live camera feed from Larix.

FAQ
Why does Larix disconnect from YouTube?
The cause could be the saved ingest URL or key, the phone or encoder, the outbound network, or a problem receiving the stream at YouTube. Watch Larix and Live Control Room during a test to locate the failure before changing settings.
Will a new stream key fix repeated disconnects?
Only if the current key is wrong, stale or otherwise the cause of the connection failure. YouTube recommends updating the encoder with a new key when a third-party encoder cannot start; changing a valid key will not fix weak upload or device load.
Should I turn on every Larix reconnect option?
No. Controls vary by platform and app version, and some described options are iOS-specific. Check Softvelum’s current guidance for the control your app actually exposes, and remember that retry behaviour cannot make an unstable connection reliable.
What upload speed do I need?
There is no single speed that suits every stream, because bitrate, competing traffic and connection stability differ. Measure upload on the same device and route, compare it with total stream bitrate, and use YouTube’s recommended 20% headroom as guidance rather than a guarantee.
