I have the same problem. However the workaround run as administrator doesn't solve the problem. It still says servers are unavailable.
I even cleaned the cache of origin, but problem still persists. please note that i had upgraded to windows 10 recently and returning to the game after last played in 2014 july.
after the updates i cannot connect to multiplayer game due to this server error, i assume it's not a real message as my friend is able to connect from same network.
please advise, my operating system is 64 bits
