fair point, here post made on other site:

they forgot refresh session if state "login failed" along "closed".

if want to, can import facebook sdk eclipse , change line 63 of fblogin.java from

if (sessionstate.closed.equals(session.getstate())) {             session = new builder(fb.getunityactivity()).setapplicationid(session.getapplicationid()).build();             session.setactivesession(session);         } 

to

   if (sessionstate.closed.equals(session.getstate()) || sessionstate.closed_login_failed.equals(session.getstate())) {                 session = new builder(fb.getunityactivity()).setapplicationid(session.getapplicationid()).build();                 session.setactivesession(session);             } 

then export project jar, including class files, classes.jar in plugins/android/facebook/bin folder.

edit: might easier if upload classes.jar i'm using... download here: http://speedy.sh/qpgup/classes.jar , put in plugins/android/facebook/bin folder.

edit 2: if still having issue, facebook seems have released fix on october 20th 2014. updating newest sdk fixes issue!
