Hey, folks
I wanted to see if this worked for anyone else. Sometimes, we get the error "An unknown error has occurred." It is so generic that it could be caused by many things.
When u enter ranked squad, ready up fastly before the error sign shows up. When u do that, the error sign should still be on the screen.
Now don't click anything after u have already readied up, with the error still on the screen. Let the game load by selecting your position for u, all while the error message is still on the screen.
Now, once it has selected ur position for u automatically, the game will load u and ur team onto the field, and boom, the error message is gone for good. If it ever comes up again, same thing....ready up fast, before the error message shows up, and let it select ur position for u, without clicking off the error message.
Once it loads onto the field, the error message is gone. I was off the game for a whole 2 months cause of it. You just gotta be patient, that's all.
