What this means
The authentication server returned a general server error.
The sign-in service returned a general server error without a more specific cause. Retry later once; if RexiMemo's website is healthy and the code repeats, contact support.
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.
