What this means
The authentication backend could not log in.
The authentication backend could not complete its own login step. It is usually beyond the console's local Wi-Fi configuration once DNS and Internet connectivity are confirmed.
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.
