Troubleshooting
Fix LM Mini connection errors, Home sync, context-full chats, voice, tools, and common setup issues.
Answer first
Most issues are the wrong provider, a bad URL, or a model that does not support the feature (tools, vision, reasoning). Check provider first, then URL/token, then the feature toggle.
Can't connect to LM Studio
- Settings → Provider is actually LM Studio (on-device/cloud will ignore that URL)
- In LM Studio, the server is running and Serve on Local Network is on
- Phone and PC share Wi‑Fi (guest / AP isolation blocks LAN)
- URL looks like
http://192.168.x.x:1234— neverlocalhoston the phone - If LM Studio requires auth, paste the API token
- VPN/corporate filters — try without VPN, or use remote access
No model at all? Use Get Started to download an on-device pick or connect a computer — Getting started.
Connect
On Mac: LM Mini Home → Share with phone. Connect for Mac is deprecated through the end of 2026.
- Re-scan the QR (old pairings go stale after reinstall)
- Confirm the Mac can chat locally first (a model in Home, or LM Studio/Ollama on that Mac)
- Keep Share with phone running — menu bar is enough; don’t quit Home
- Windows/Linux: LM Mini Connect 1.5+ (newer QR for multi-backend)
Phone and Mac sync
Toggle lives at Settings → Remote Access → Sync chats with Home (Home pairs only).
- Share with phone is on
- Toggle sync off and on to retry
- You should see “chats and folders are now in sync”, or a prompt to open Share with phone
Sync copies chats and folders, not settings or models. Guide: Phone and Mac sync.
On-device model won't start
- Download finished (not paused) and selected in the on-device picker
- Enough free storage and RAM for that quant
- MLX-only models need supported Apple Silicon; otherwise pick GGUF
- After download on Android, open a new chat if an old empty-model state lingers
Context is full / prompt too large
- Check the context bar in chat
- Settings → Models → When context is full → Roll or Cut middle, or use Compact
- Or start a new chat / pick a model with a larger window
Details: Chat — when context is full.
Tools / Pro Search do nothing
- Enable tool use is on
- Model advertises tool calling (try a recent instruct model)
- Pro Search needs Pro where required
- SearXNG URL reachable from the phone
- Watch the transcript for tool rows — if absent, the model never called a tool
Voice / mic problems
- OS microphone + speech permission granted
- Correct STT language
- Kokoro on Mac needs Share with phone (Home) or Connect on Windows/Linux, plus Kokoro actually running
- On Mac Home, allow Speech Recognition in System Settings if Mac system STT is silent
- Call Mode is iOS-specific — use continuous conversation elsewhere
Image generation errors
- Backend URL reachable (A1111 API / ComfyUI)
- Workflow is API format for ComfyUI
- Checkpoint / LoRA names match files on the server
- On-device SD only on builds that ship Core ML assets
App Lock / forgot PIN
- Settings → Data → App Lock is a Pro setup. If the lock is already on, it still asks for the PIN after Pro lapses.
- Wrong PIN: wait if the app briefly blocks more tries, then try again.
- There is no forgot-PIN reset. Reinstall LM Mini to clear the lock. The PIN is not in iCloud, Home sync, or cloud backup.
Guide: Settings — App Lock.
