How to Fix Nintendo Switch Error Code 2110-3127?
If your switch can not connect to a wired or wireless network, the Nintendo Switch error code “2110-3127” occurs. Whenever you connect to a network, a series of checks are carried out in the background, such as DNS checks, Internet connectivity checks, etc. If any of these are not met, the error message will be sent to you.
The reasons for the error code “2110-3127” are mainly related to problems with internet connectivity where the entered DNS may not work or the type of encryption does not work with the specified wireless network. The complete error message contains the message “Connection test failed. DNS name resolution could not be performed. Please try later again.’
What causes Nintendo Switch Error Code 2110-3127?
As mentioned, the error code is mostly associated with connectivity problems, but not limited to them. Some reasons are as follows:
Make sure you have an active internet connection before proceeding with the solutions. You should check the network from other devices like your computer or smartphones. If you can normally access the internet, the possibility of limited connectivity is exceeded and Nintendo Switch-specific solutions can be used. Also, make sure you don’t use the Internet at all. There is a firewall in these networks that blocks some requests.
Solution 1: Power Cycling Nintendo Switch
The solutions that worked for most people were the Nintendo Switch’s power cycle. As discussed above, your switch may contain bad network configurations in numerous cases. Reconnecting to the network doesn’t erase them, but you have to power your device completely.
Solution 2: Manually Entering DNS Settings
Domain Name System is a name system for all Internet access devices. Whenever you type “google. com” in the address bar, the name is “resolved” by the DNS in an IP address and the Internet communication starts. This is more or less the core of internet connectivity. If the DNS does not work automatically, we can manually try to enter it and see if the problem is resolved. We’re going to use DNS from Google.
DNS Settings: Manual
Primary DNS-Server: 22.214.171.124
Secondary DNS-Server: 126.96.36.199
Solution 3: Manipulating Security Settings
Another way to fix the issue is to manipulate your network’s security settings. Several users reported that the problem was solved again by switching from WPA2-PSK to WPA-PSK. This is a strange behavior that means that when the configurations are reset, there is a bug in the switch that is resolved.
Solution 4: Troubleshooting the Network
If the error code 2110-3127 persists even after all of the above steps, there is probably a problem with the network you are trying to connect. You should try using another device to connect to the internet via the network and verify that it is actually operational. If it’s not, further troubleshooting is needed.
You can even try to connect with your switch to another network / router and see if the problem persists. If it doesn’t, your router will have a problem and you have to reset the settings. There may be problems with your ISP or even firewalls that could cause the problem. Make sure you solve the problem thoroughly and try to connect Switch only if your network works perfectly.
