Switch Servers > Connection Test

This server is used to check if the internet connection is working when you connect to a wifi network.

The server supports both HTTP and HTTPS. The Switch uses the former.

If HTTPS is used, the server certificate is signed by Nintendo Class 2 CA - G3.

The following request is sent to the server by the Switch:

GET / HTTP/1.1
Host: ctest.cdn.nintendo.net
User-Agent: NX NIFM/00
Accept: */*
Connection: keep-alive

The server replies with the following response:

HTTP/1.1 200 OK
Content-Length: 2
Expires: Mon, 05 Apr 2021 14:52:05 GMT
Cache-Control: max-age=0, no-cache, no-store
Pragma: no-cache
Date: Mon, 05 Apr 2021 14:52:05 GMT
Connection: keep-alive
X-Organization: Nintendo
Content-Type: text/plain

ok

If the user agent does not start with NX NIFM/ the server sends the following response instead:

HTTP/1.1 403 Forbidden
Server: AkamaiGHost
Mime-Version: 1.0
Content-Type: text/html
Content-Length: 275
Expires: Mon, 05 Apr 2021 14:53:52 GMT
Date: Mon, 05 Apr 2021 14:53:52 GMT
Connection: keep-alive
