Nintendo error code 2123 is generally a short-term network problem. Still, if the failure persists, it is necessary to determine if you have the latest version.

Why do Nintendo Switch Error Codes 2123 occur?

The Switch error code 2123 shows up when trying to connect to the Internet, download software, or launch a downloaded game. It is an issue related to your internet connection, and it can appear in Fortnite or other games.

How to Fix

1. Let’s try downloading it again.

  • The first thing you need to do is click OK to close the error message.
  • When you get an error message that says Download is stopped, you can click Continue to try again.
  • Nevertheless, if error code 2123-1502 appears again, we recommend you try continuing the download several times, since many users reported that this fixed the error.
  • The Download should now be complete if you get a Downloading data message.

2. Turn on and off Nintendo Switch’s Flight Mode

When the Nintendo Switch is in flight mode, a temporary communication glitch may cause the error by reestablishing communication between the communication modules.

  • Open Nintendo Switch’s System Settings and select Flight Mode (or Airplane Mode).
  • Wait 1 minute after enabling Flight Mode in the right pane.
  • After that, disable Flight Mode and see if the download is successful without showing error 2123-1502.

3. Switch the console off and on again.

Press the POWER button three times, then select Power Options, followed by Turn Off. Once the console has turned off, press the POWER button again to turn it back on.

4. Switch to another language on the Nintendo Switch

An issue with the user interface (especially, language modules) of Switch might stop the download from completing. If this is the case, changing Switch’s language and then reverting to your preferred language might fix it.

  • Open System Settings on your Nintendo Switch and click System.
  • Do not leave the screen, otherwise, you won’t be able to change the language back.
  • Check if the Switch is clear of error 2123-1502 after changing the language to your preferred language (like English).
