Latest Switch firmware update still causing issues, support page updated to help with error

The latest firmware update for the Nintendo Switch, which was redistributed last week amidst some technical hiccups, is still causing some annoying issues for many players. Version 12.0.3 may not have brought much more than some beloved stability (or not, in this case…), but it’s now being blamed for error code 2123-1502 which crops up while trying to download software from the eShop; some folk are running into problems when downloading DLC for their games, too. Well, Nintendo have updated their support page which outlines some workarounds presumably while they try and develop a further patch to iron out these annoyances.

Here’s what Nintendo are suggesting if you run into error code 2123-1502:

  • Attempt the download again
    1. Select OK to close the error message.
    2. A message indicating that the download stopped because an error has occurred may appear. Select Continue to attempt the download again.
    3. If the same error code appears again, please try continuing the download a few more times.
    4. When the message “Downloading data…” appears, the download should complete normally.
  • Restart the Nintendo Switch console.To restart the console, press the POWER Button for three seconds, and then select Power Options, followed by Turn Off. When the console has turned off, press the POWER button to turn it back on again.
  • Clear the cache on the Nintendo Switch console.
  • Test your internet connectionTest your internet connection to ensure that your Nintendo Switch is still connected to the internet.
  • Create a new internet connection.Set up a new internet connection, ensuring that you are attempting to connect to the correct network, and that you are receiving a strong wireless signal from the network.
  • Manually enter an alternate DNS.If the DNS you are attempting to use is not working, entering an alternate DNS may resolve this issue.
  • Ensure that the MTU value in your network settings is set to default (1400).
  • Connect to the internet at a different location or access point.

This may be related to a temporary network issue. Please wait a while and try again at a later time.

  1. Yeah My system tried to update Bomberman Online – and I just get the X flashing – tried numerous times to do the steps that Nintendo are advising and nothing is working …

  2. Ah I was dealing with that issue the other day. Glad to know they are aware and are working on it. I was able to make it work by just leaving my switch on and staying on the download popup. Then it didn’t error out anymore.

  3. Nintendo finally did the unthinkable. They released a stability update that made the Switch less stable!

  4. For anyone having this issue go into the internet settings and change the DNS from auto to manual and set it to use google DNS for the primary and for the 2nd

  5. I’ve had this happen multiple times now. I bought Game Builder Garage and upon closing out of the eShop its home screen icon just had an X over the download bar. At first I thought maybe I had less space on my microSD than I remembered, but no, I had ten times what the file size is. Then it happened again with another game I bought and then an update for another one. I never thought the system update was the culprit though.
