What Is The Error Code 2123

Error code 2123 is an error that can occur when you are using the Nintendo Switch. It usually appears when trying to access an online service, such as the Nintendo eShop, or when trying to download or update a game or application. 

When you see error code 2123, it means that there is a problem with your internet connection or with the Nintendo servers. It can also be caused by issues with your Switch itself, such as a software bug or a hardware problem.


What Causes The Error Code 2123

Before we dive into the potential solutions for this error, it’s helpful to understand what might be causing it in the first place. The error code 2123 can be caused by a variety of factors which have been explained below. 


Reason#1) A weak or unstable internet connection

If your Switch is connected to a weak or unstable network, it can cause the error code 2123 to appear. This is because the Switch relies on a stable internet connection for many of its features, such as online multiplayer, eShop purchases, and downloading updates.


Reason#2) Server issues

If Nintendo’s servers are down or undergoing maintenance, it can cause the error code 2123 to appear. In this case, you will just need to wait until the issue is resolved.


Reason#4) Outdated software

If you’re using an older version of the Switch’s firmware or a specific software, it could cause the error code 2123 to appear. In this case, you’ll need to update the software to the latest version to resolve the issue.


Reason#5) Corrupted data

In some cases, the error code 2123 can be caused by corrupted data on your Switch. Various factors, such as a power outage or a software glitch, can cause this.


How To Fix The Error Code 2123

Now that we have a better understanding of what might be causing the 2123 error, let’s look at some ways you can try to fix it.


Method#1) Restart Your Nintendo Switch

The first solution is simply restarting your Switch. Sometimes, a simple restart can resolve the error code 2123 and allow you to access the feature or function you were trying to use.

To restart your Switch, follow these steps:

  1. Press and hold the Power button on the top of the Switch for a few seconds.
  2. When the power menu appears, select Power Options.
  3. Select Restart.
  4. Your Switch will shut down and restart. 
  5. Once it’s finished restarting, try the operation again and see if the error code 2123 has been resolved.


Method#2) Check Your Internet Connection

If restarting your Switch didn’t fix the error code 2123, the next step you should take is to check your internet connection. As mentioned earlier, the error code 2123 can be caused by a weak or unstable internet connection.

To check your internet connection on your Switch, follow these steps:

  1. Go to System Settings on the home screen.
  2. Scroll down and select Internet.
  3. Select Internet Settings.
  4. Select your current Wi-Fi network.
  5. Select Test Connection.

The Switch will perform a test to see if it’s connected to the internet. If the test is successful, it means that your internet connection is stable, and the error code 2123 is likely caused by something else. If the test fails, it could indicate a problem with your internet connection.


Method#3) Download Again

If the game won’t download and persists with the error 2123-1502, it may be due to some bug in the Switch-server handshake protocol.

You can resolve the issue by attempting to download it all again. First, however, make sure you have enough space to finish the download on your Switch.

  1. Select Cancel to halt the downloading process. 
  2. Next, press the Download button again.
  3. The downloading process should now start. Wait and let it complete.
  4. If you still see an error, press Cancel again.
  5. Download again and keep retrying until it downloads.
  6. The problem should now be resolved.


Method#4) Clean the Cache

Clearing the cache usually fixes most problems as it clears out any corrupted files that might be halting the download process and causing errors. It’s also pretty easy to do and takes minimal effort. 

You will not lose your saved data and games if you only clean the cache and not resetting the whole system. Cleaning the cache will only get rid of useless, bugged files.

  1. Press the Home button on the Nintendo Switch to open Settings. 
  2. Go to System Settings
  3. Go to System
  4. Scroll down to find the Formatting Options. They should appear towards the right of the screen. 
  5. Select Reset Cache. 


Method#5) Update The System

Sometimes the error can be caused if you’re using an outdated version of the firmware, as this makes it incompatible with Nintendo servers.

Ensure your software is updated, as this can fix most problems in the system, including error 2123.

  1. Open System Settings
  2. Then, go to the System tab.
  3. Select System Update. Wait for the update to install.
  4. Restart your Switch after the update has finished.


Method#6) Reset the Nintendo Switch

If you’ve tried all the aforementioned options and the problem just won’t disappear, you should try resetting the Switch to its factory settings. This will remove the error if your Nintendo firmware has been severely corrupted.

Before you start, we suggest you back up your data to avoid losing any saved progress.

Moreover, power off the Nintendo Switch and remove the SD card.

  1. Open System Settings
  2. Go to System.
  3. Then, click on Formatting Options. You may be asked for the PIN.
  4. Click the Initialize Console option. 
  5. Before moving forward, make sure your data is backed up.
  6. Press Next. Select Restore Factory Settings.
  7. Wait for the process to be completed.
  8. Reprogram the Switch as you please and set it up. The error will now likely be gone, and you will be able to resume your normal activities.
