My ISP is Dodo (australia). Ever since the 11th of september or so i haven't been unable to play because of a cattle error i have been getting at the title screen . I've reset the router/console, opened ports and blah blah the list goes on and nothing solves the issue. I can however easily log on and play the game without errors if i use my nokia's wifi hotspot. This leads me to believe that my isp is playing hardball and that the game and my ISP don't agree on something. I play on the XB1, my ISP is Dodo as i have already mentioned and i use a netgear router/modem. I think it may be a good idea to chat to them as i know a few other people using the same ISP as me have the exact same issue.
