Nintendo Switch Online error 2110-3127
Connection test fails because of DNS
The console cannot get online over Wi-Fi or a cable. Nintendo says this code points to a DNS problem, either a wrong DNS entry on the console or trouble at the provider.
How to fix error 2110-3127
Restart the console.
In your saved network's settings, set DNS to Automatic unless your network needs a manual one.
Power cycle your modem and router.
Enter 8.8.8.8 as primary DNS and 8.8.4.4 as secondary DNS to test another DNS.
Try again later in case your internet service is having trouble.
