Hi @PenguinLord355,
What are you seeing when you're trying to join a match? Is the game freezing up, or is it giving you any error messages? If you're getting an error, what is the full error message?

Thank you for the updates!
It's possible the connection is timing out before it can connect you to a match. There are a few things we can try which might help with this. When you have the chance I'd recommend starting off with the basic connection steps from the EA Help website to see if that helps.
If you're still running into the same issues after that please let me know. Thanks!

Thanks for following up!
I'm afraid our Switch-specific troubleshooting is a bit limited compared to other platforms. One thing that could help is forwarding the ports for the Switch on your router/modem. The Nintendo Support website has instructions on how you can do that.
If you're able to give it a shot please let me know how it goes. Thanks again!

Thanks for following up and letting me know. I'm glad to hear you were able to play!
