Troubleshooting
This section is indexed by symptom, not subsystem. When something is wrong on a show floor, you don't search for "WebSocket reconnection logic" — you search for "sign shows offline." Pick the symptom that matches what you see and follow it down.
If none of these match, see Getting Support for what to capture and where to send it.
Always capture before you reboot
Before rebooting a misbehaving sign, fetch its logs from the dashboard (Remote Control → Fetch Logs). A reboot that fixes the symptom also destroys the evidence.
