OP already mentioned the endpoint for their account and their wife's differ; if the destination IP is based on what server holds the character data and the issue crops up on the wife's computer, it could still be that there's some misconfigured rule somewhere along the line that causes issues going to that IP and not the other one. Which would mean it would be account-specific but still not the SquareEnix servers directly.

Hence the VPN suggestion, since it'll presumably eliminate one more possibility. I'm not expecting it will, but... hey, more data is always good.
