I have this Origin issue too with the internal server error message, but I can still play the game. THere is a message out when trying to reach EA support, saying that they work on the issue.
But since yesterday I can't login to answers hq. I'm logged in here but some how does not correctly travel over anymore. It still says to sign in even though I am technically signed in. I tried on my mobile but does not work either. I'm not the only one with this issue and don't really know where else to post this since we can't post there.
