Please work through the following steps to see if they fix the problem:
🛠 Check if server maintenance is happening.
Notifications for server maintenance will appear in game as well as on our social channels.
🛠 Make sure you have enabled CROSSPLAY.
In your game options, select the Game tab and make sure that the Enable Crossplay box is checked for both players.
🛠 Make sure you are on the latest game build.
If an update was released recently, you will need to be on the latest build to play with the rest of the community.
🛠 Make sure your local or campus firewall is not blocking connections.
Make sure the game is whitelisted so it doesn’t get blocked in the matchmaking lobby.
🛠 Make sure the computer meets the game's minimum system requirements. The minimum system requirements can be found here. One of them is Windows 10 64bit.
🛠 Check for pending Windows updates. Verify that there are not any pending Windows updates.
While you may be on an up-to-date version of the OS, there may be essential application updates waiting to install. Be sure to restart your device after installing any updates.
🛠 If you are running the Windows ‘N’ or ‘KN’ version of Windows 10, install the Media Features Pack.
