“Could not find a server that was suitable for all members of your fireteam.”

I’m alone, and every matchmaking gives me this message.

I think I fixed it. It seems to have been a big with my Xbox. I had to check the Multiplayer connection, and then the message goes away.

Glad to see you got your issue solved OP, feel free to open another topic if you still need help with anything. Worth noting that there did seem to be a few issues with matchmaking earlier, hopefully that’s passed now
