Can't login/Disconnected from Server

I tried to find some answers from the Forums, but can't seem to find anything...but anyways, everything loads fine until I try to login. I keep needing to put in an Authentication Code, but every time I do it, a message pops up saying "Disconnected from the Server". (I have my phone connected to my email so I don't have problems making sure I don't take too long, but....) *Also it's been a while since I last played, so I'm not sure if I need to do anything about that...*
