Just bought a PS4 and my friend let me borrow his copy of Black Flag. But whenever I try to login to their servers I get a message telling me "Ubisoft servers unavailable." Whatever, I don't really care about that. But the problem comes in when I get in-game and I get a giant error message every 30 seconds on the side of the screen telling me "Connection error. Your connection to the Ubisoft servers has been lost."

Is this a used copy problem? Or is there some way to fix this?

It does have an online pass but it shouldn't be doing that, maybe disconnect your PS4 from the internet when you play it?

I will try when I get home. But I would rather be able to play while connected to the internet.

I believe the online pass is strictly fleet missions/cosmetic stuff; you should still be able to play online. Server could be down.
