Frequently Asked Questions

Does error 2124-4080 mean my Switch is banned?
No, this error is related to a communication interruption, not a ban. It typically occurs due to network issues or game server problems.
Will I lose my game progress if I reinstall the software?
No, your save data is stored separately on the console and will remain after deleting and reinstalling the game. However, always back up to the cloud if you have Nintendo Switch Online.
Does this error happen on all games or just one?
It can occur on any game that requires an internet connection. Check if the error appears on multiple games; if it does, the issue is likely with your network or console. If only one game, the problem may be with that game's servers or installation.
How do I update my Nintendo Switch if it won't connect to the internet?
If you cannot connect to the internet, try using a wired LAN adapter (sold separately) or a mobile hotspot for a one-time update. Alternatively, you can update the system via a local transfer from another Switch.
What if my router's NAT type is D or F?
NAT types D and F restrict online connectivity. You need to change your router settings to achieve NAT type A or B. Enable UPnP or configure port forwarding for the Nintendo Switch (ports 1024-65535) to improve NAT.
