The trap with LG's error 137 is treating it as a dead internet connection and resetting your whole network. It almost never is. On webOS, 137 is app-scoped — the TV has network access, but one specific streaming app (most often YouTube) can't reach or load its content server. The tell is simple: if everything else streams and only one app throws 137, your network is fine and the app is the problem. So you fix the app first.
Fix it
- Reinstall the failing app and clear its cache. This is LG's own remedy and the highest-yield step. Uninstall the problem app (Home → highlight the app → uninstall), then reinstall it from the LG Content Store. That clears the stale app state behind 137.
- Reset network settings if more than one app is affected: Home → Settings → All Settings → General → Network → Network Status → Reset Network → Yes.
- Set DNS manually when 137 tracks with a flaky ISP: All Settings → General → Network → your connection → Advanced/Edit → IP Settings (Manual) → DNS
8.8.8.8/8.8.4.4(Google) or1.1.1.1/1.0.0.1(Cloudflare). - Power-cycle the TV and router. Unplug the TV and hold its physical power button 30–60 seconds to drain residual charge, unplug the router ~3 minutes, bring the router fully back up, then power the TV on.
- Update firmware. Settings → All Settings → Support → Software Update. This clears bugs that start throwing 137 after an app update.
The gotchas worth knowing
- It's usually YouTube. Reinstalling that one app clears 137 while everything else keeps streaming — proof it's app-layer, not your connection.
- Low storage breaks app updates. If the TV is low on space, apps can't update or cache properly and start failing. Freeing space (or reinstalling) fixes those.
- A small share really is weak Wi-Fi. If reinstalling doesn't help and the stream buffers mid-play, that subset is a signal problem — a DNS change or a wired connection helps where an app reinstall won't.
How it differs from LG's other network codes
This is the part that saves you time. Per LG's own error list:
- 105 — Wi-Fi not connected (adapter/settings)
- 106 — weak or intermittent Wi-Fi signal
- 201 — general network connection error
- 202 — no internet connection
- 137 — an app failed to load; the network itself is fine
105, 106, 201 and 202 are network-wide. 137 is the only one scoped to a single app, which is exactly why app-level fixes (reinstall, clear cache) beat network-level fixes for it.
FAQ
Does error 137 mean my Wi-Fi is down? No. If only one app fails and others stream, your network is fine — 137 is that app failing to reach its server.
Why does reinstalling YouTube fix it? Because 137 is usually stale app state, not a connection fault. A clean reinstall from the LG Content Store resets it.
It came back after an app update — normal? Yes, that's a common trigger. Reinstall the app and make sure the TV isn't low on storage.
