I have this error too when I typed a wrong password to connect to the green 'osjs' interface. have you changed the password of your board ? have you tried the 2 possible passwords ( "arduino" or "doghunter" ) depends on the image installed ? hacve you cleared your browser cache / test with another browser ?
