Explanation
What this error means
Error 2124-4007 (alongside 2124-4508) appears with a message that online use is restricted, and Nintendo states it indicates the console has been permanently banned from connecting online for breaching the user agreements. It’s an account/console restriction on Nintendo’s side, not a connection fault — and local network changes won’t lift it.

Repair
How to fix it
Ordered easiest-first. Try the next step only if the error comes back.
-
Understand what the code means
This is a console-level online ban, not a connectivity problem. Offline play still works, but online features (eShop, online play, updates) are blocked.
-
Don’t expect a network fix
Restarting, changing DNS, or re-adding the network won’t lift a ban — the restriction lives on Nintendo’s side.
-
Contact Nintendo Support
If you believe the ban is a mistake, or you bought the console second-hand and inherited it, contact Nintendo Support to explain and ask about your options.
-
Check the console’s history if bought used
A used console may have been banned by a previous owner. Nintendo Support can confirm the status tied to the hardware.
Escalation
When it's not your fault
Signs the problem is on Nintendo's side — or in the hardware — rather than anything you can change:
- You bought the console second-hand and never modified it — the ban may pre-date your ownership.
- You’re certain you haven’t breached the user agreement and suspect an error.
- Only online features are blocked while the console otherwise works normally.
Questions
FAQ
Can I remove this ban myself?
No. It’s a console-level restriction on Nintendo’s side. No network change, reset, or DNS tweak will lift it — only Nintendo can review it.
I bought the console used — what now?
Contact Nintendo Support and explain. Bans follow the hardware, so a previous owner’s actions can affect you; support can confirm the status and options.
Does the console still work offline?
Yes — offline single-player generally still works. The restriction blocks online services like the eShop, online play, and updates.
