What this means
Nintendo Wi-Fi authentication could not complete.
The Nintendo Wi-Fi authentication stage failed without a more specific reason. First confirm the console has working Internet access, then verify the active connection still points at RexiMemo's DNS.
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.
