i'm working on Odoo 8 in a multiprocessing Mode with nginx as a proxy server, i read a lot of issues about this error but i still can't fix my problem,i think that i couldn't run the odoo in a gevent mode, i already configured the nginx with the longpooling location as many posts said my config is as below:-

nginx config:-
