You're not alone. I live in Sweden though. My game worked basically flawless until I decided to have a break right after some time when the Dragon's teeth DLC came.
Now some more people want to play (they don't have any problems) I get this all the time. Sometimes I can enter a match but not finish it properly bc I get kicked with this message.
I opened up all the ports I read on the forums / youtube etc.
The funny thing it has always worked.. I was FORCED though to download a bug update around 3GB (3.17GB i think) or else I was not allowed to play MP.
I'm frustated >.<
