Getting the Error Message: Your External IP Address has changed since you last authenticated.
This error can be caused by a few things such as a mobile broadband connection or connecting from a secure location such as work or a university connection. These types of connections will often route your login traffic through a secure proxy which returns one IP address to us and then when you connect to our game servers they will not route that through the same proxy as it doesn't involve secure data and so it returns a separate IP address to us.
