Requires a one-time DNS change — takes about 3 minutes
The server has a whitelist. You can't connect until the admin adds you. Tell them your Xbox gamertag — the name attached to the Microsoft account linked to your Switch. They'll add you before you try to connect.
Your gamertag shows up on the Switch under System Settings → Profile. It's the name next to your icon.
From the Switch home screen, open System Settings (the gear icon).
Scroll down to Internet, then tap Internet Settings. Your WiFi network will appear.
Tap your WiFi network name, then tap Change Settings.
Scroll down to DNS Settings and change it from Automatic to Manual.
Primary DNS: 104.238.130.180
Secondary DNS: 8.8.8.8
Tap Save, then tap Connect to This Network to reconnect.
From the Switch home screen, open Minecraft.
Tap Play, then the Servers tab.
Tap on any of the featured servers (Lifeboat, Mineplex, etc.) — it doesn't matter which. BedrockConnect will intercept it.
A screen appears asking for a server address. Type:
Server: goats.sortoflikethis.com
Port: 19132
Tap Submit.
The game should load and connect you to the Goat Server. If it says "You are not whitelisted," the admin hasn't added your gamertag yet.
