cannot play fc 24 ultimate team on rivals match.

Thank you.
Based on the information you provided, it's likely to be an issue with the game itself that needs to be reported to the game developer (EA).

However, before doing that, I could suggest these potential solutions:

A. Make sure your NAT type is set to open.
You can check your current NAT type by going to Settings > Network settings.

In case your NAT doesn't say “open”, I can suggest you to open it by contacting your ISP and asking them to open the following ports:

Port 88 (UDP)
Port 3074 (UDP and TCP)
Port 53 (UDP and TCP)
Port 80 (TCP)
Port 500 (UDP)
Port 3544 (UDP)
Port 4500 (UDP)

B. Connect your Xbox to a different Wi-Fi network, like a mobile hotspot.

C. Open settings on your console > select network settings > advanced configuration > DNS configuration > select manual.
Insert this IP address 1. 1. 1. 1 and then this other one 1. 0. 0. 1.

Restart your console before trying to again.

Note: You may want to try with 8. 8. 8. 8 and 8. 8. 4. 4 as well.

D. Reinstall the game.

Furthermore, I think you may find the following topic useful. There, you can analyze when it is necessary to contact Microsoft support or the dedicated game support:

I play on xbox, I do have access to any other online features available in this game except only on ultimate team rivals match, no other games affected just FC 24 Ultimate team on rivals match. The message that I see every time before launching the match is You lost your connection to your opponent. We'll check the match report to see who won and who lost. The potential solutions I have tried to solve this issue is restart my internet router reset my console restart my console try to play a different games still not working. I do searching online some other having the same issue like me.

it was fifa 23 and yesterday i got into ea sports fc 24 ultimate team but today i was unable to connect

U know, I was noticing the same thing, I had Chelsea FC as my team but I was staring to play with FC Barcelona and I was only playing againt Real Madrid and just a few matches with teams like PSG or MUFC...I think that this FIFA 13 has some type of calculating
the overall of the players of every team that those number gotta match or be similar to your opponent because I started playing with my team I choose "Chelsea FC" and I have never again played again Real Madrid or teams with many players with a 90+ overall
player...hope u understand me, but that's what I been noticing!..
