Somehow, that connection was logged out (or never fully logged in) which is what is causing the issue. (I can tell because the _http* variables are also not initialized). Did you do anything prior to this happening (open and close windows, test connections, ...) that might have caused this? Does this only occur with that particular connection?

I edited and tested connections (see #131).
