Hmm… your 3 screenshots labeled Disconnect #1 through Disconnect #3 in your original post all show two TCP connections disconnecting. Your screenshot in another thread also shows two connections.

I have no idea whether it’s normal for a FF XIV client to have two connections, or it’s only two connections for a while after you change zone/dungeon/instance/whatever.
