What this means
The console sent invalid authentication data.
The console sent authentication data that the sign-in service considers invalid. This is an authentication-layer data error, not a normal RexiMemo page error. Retry once after a reboot and report it if it is reproducible.
What to try
- Retry once after restarting Flipnote Studio. A one-off failure can be temporary.
- If the DSi connection test succeeds, avoid changing unrelated Wi-Fi settings.
- If the same code keeps returning, contact RexiMemo support and include the complete code and the action that triggered it.
