How To Fix ‘Nintendo Error Code 2123’

If you receive the error 2123-1502 on your Switch, it signifies that your console is unable to maintain a constant connection to the Nintendo servers, and as a result, you are unable to download (or update) any software for your Switch.

Method 1: Use the Download Menu To Retry The Download.

Error 2123-1502 during a failed download of an app or game may be due to a short hiccup in the handshake protocol between the Switch and its servers.

The problem may be resolved by retrying the download from within the Download Options. Make sure there’s enough free space on your Switch before continuing.

Step 1: Start by clicking Cancel to stop the download, then try again by clicking the download button (you may keep spamming the download button 15 or more times). Don’t interrupt the download once it has started.

Step 2: If the error message keeps appearing, try cancelling the download by clicking Cancel, then retrying the download when the button appears.

Step 3: After that, rapidly go to Download Options (so the problem doesn’t appear) (or Download Settings).

Step 4: Please be patient while the backdrop download finishes. Avoid applying any pressure to the system at any point. A Download Successful notification will appear in the top left corner of the screen after the download is complete.

Step 5: If that doesn’t work, try restarting the download while the switch is docked to see if it helps.

Whether the problem persists after that, try seeing if updating or installing a new app or game from the Step 6: E-shop fixes it.
