I've done some testing. If I use a VPN connection and connect via USA everything works. But If i connect from Germany, sweden etc it dosent.
Something wrong with EU servers?
I'm having the exact same problem with PVZ Garden Warfare.. however, where I'm getting the error message is on the Xbox 360. My son has the S Series and it works perfectly fine on that. I'm in the UK too, so if it's the EU servers, why will it work on one console and not the other? I'm trying to find his 1S because we have it installed on that one too, to see if it will work fine on there. It's bamboozled me no end!
Both GW1 and GW2 are suddenly back up and working on our XBox X. Really odd - I'm not sure what happens at the server end but I can only assume its something wrong at that end because I haven't changed anything on my xbox or the network configuration or port forwarding etc.
It just started working again all by itself.
