I have seen other people post this but I will go ahead and post it from my view as well.
I got the "Server disconnected" error after I finished the 2nd chapter. I relogged in and ran it again and disconnected again.
But, then I ran the chapter before (Chapter 1) and after it (Chapter 3) and I had no disconnect. So, I am not sure whether if the server is messing just on that chapter or there is something about that chapter that needs to be looked at in terms of connection wise.
Other than that, that is all I have for now. If the disconnect persists, I will provide screenshots but it is the same case that has been addressed already quite a bit in this thread.
