Hey @birthdayguest,
I know that dealing with disconnections like this is really frustrating, especially when you're playing ranked. Can we try running through some troubleshooting steps to see if we can help stop this from happening again?
When you have the chance I'd recommend starting out with the basic connectivity steps from the EA Help website to see how that goes. If you're still running into the same issues afterward check out the Xbox-specific steps as well. Let me know if you're still getting any of the same error messages after that.
Thank you!
