I want to second the OP's issue. I'm using the latest version of Chrome & I'm still unable to access FOP2. After logging in, I just hang at the "One moment please, connecting to server" screen. Opening up the JavaScript debugger, I see the following:
intento conectar web socket en ws://192.168.1.5:4445
http://192.168.1.5
Invalid UTF-8 sequence in header value
ws close event
close event
on close reseteo a cero
Over and over again.
IE9 & Firefox both work fine.
