Troubleshooting & support
Most issues have a two-minute fix. Start here — if you still need a human, we are one email away.
Common issues
| Symptom | Fix |
|---|---|
sonderr: command not found | ~/.local/bin is not on your PATH. Add it as the installer instructed and open a new terminal. |
| Workspace on an unexpected port | Port 4173 was busy — Sonderr automatically moved to the next free port. Check the terminal output for the actual URL, or force one with sonderr --port 4300. |
| Browser did not open | Start with sonderr --no-open and open the printed URL manually, or just visit http://127.0.0.1:4173. |
| Workspace is locked with an update prompt | That is the required-update gate. Choose Install update & restart. If it fails, the updater restores the previous install automatically — check ~/.sonderr/update.log for diagnostics and retry. |
| Update keeps failing | Re-run the one-command installer; it preserves your previous folder as a timestamped backup and replaces the managed install. Your data under ~/.sonderr is untouched. |
| Sonderr-v1 not offered | The local model needs Linux x64 with glibc 2.34+, GLIBCXX 3.4.31+, OpenSSL 3 and libgomp. Other platforms get the merged model with the CPU-only runtime instead. |
| Free model unavailable or rate-limited | Anonymous Kilo Gateway use is rate-limited and the free lineup can change. Add a Kilo API key for the broader catalog, or switch models in the picker. |
| File tool refuses a path | Expected: symlinks resolving outside the workspace and protected paths like .env or .sonderr are rejected by design. Move real work inside the workspace. |
| Project checks will not run | Checks need Build mode, Full PC access in Settings → Tools & Access, and an explicit verification request in your current message. |
| Upload rejected | Files are capped at 20 MB and stored per-session. Images route to Vision mode automatically. |

Before you write: grab the diagnostics —
~/.sonderr/update.log for update issues, the terminal output for launch issues, and your Node version (node --version) for everything. It halves the back-and-forth.
