The first thing you need to do is make sure you are friends with the people you want to invite. You'll also need to check if your friends are online and available.
You can also invite through the Grounded lobby screen or invite directly from your platform's friends list. But if you're the one joining, you'll have to try to select your friend you want to join and press "Join Game".
Since Grounded is not free to play, your Xbox friends must have Xbox Ultimate to play it. Xbox Game Pass does not include Xbox Live Gold, which is required to play online.
Make sure your internet connection is stable or try using another connection method, even try using another network if you're using Wi-Fi and it's possible for you. This is all you need to know about how to fix Grounded multiplayer not working, so we hope we have been very helpful and we hope that you will be able to fix this problem quickly.
