Quick answer

2110-3127 points at the DNS being used. Restart the console, set DNS to Automatic if a manual value is not needed, power cycle your home network or enter an alternate DNS, and try again later.

Safety first

Stop and check this first

  • If your network requires a specific DNS (for example at work or school), do not change it yourself; Nintendo says to contact that network's administrator.

Safe checks you can perform

  • Restart the console and create a new connection
  • Check the DNS setting
  • Power cycle your home network
  • Enter an alternate DNS or try later

Leave these tasks to a qualified professional

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

    What they doHelps you update the router firmware or reset the router to its factory default settings.

    They must show youthe firmware version before and after.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Restart the console and create a new connection

    No special tools

    Who:
    you.
    How:
    restart the console from Power Options. On wireless, set up a new internet connection to the correct network with a strong signal.
    Result that matters:
    whether the connection test passes.
    If it passes:
    the console or its old connection was the issue.
    If it fails:
    check the DNS setting.
    Evidence to keep:
    connection type and the test result.

  2. Check the DNS setting

    No special tools

    Who:
    you.
    How:
    in the console's internet settings, look at DNS. If it is Manual but your network does not need it, change it to Automatic. If your network requires a specific DNS, ask the network administrator.
    Result that matters:
    whether the console connects with the corrected setting.
    If it connects:
    the DNS entry was the cause.
    If it fails:
    power cycle your home network and enter an alternate DNS.
    Evidence to keep:
    DNS setting before and after.

    Evidence: Nintendo Switch error code 2110-3127

  3. Power cycle your home network

    No special tools

    Who:
    you.
    How:
    turn your router and modem off and on again. Before testing the console, check that the network devices are back on and other devices can reach the internet.
    Result that matters:
    whether the console connects once the network is back.
    If it connects:
    the network devices were unresponsive.
    If it fails:
    go on to the next check.
    Evidence to keep:
    time of the restart and whether other devices had internet.

  4. Enter an alternate DNS or try later

    No special tools

    Who:
    you.
    How:
    manually enter an alternate DNS as Nintendo describes. If it still fails, try again later, as an issue with your internet service may clear.
    Result that matters:
    whether the console connects with the alternate DNS or later on.
    If it connects:
    the DNS service you were using was the problem.
    If it never connects:
    contact the router manufacturer about firmware and a reset.
    Evidence to keep:
    DNS values used and times of the attempts.
