I cant play agar.io anymore :(

when i play agar.io, when it automatically logs in on my google+ account (i dont have facebook), or i manually log in (i can still play as a guest or on someone elses facebook or google+ account), it says Connecting... forever and after 2-3 second the screen turns white. i tried to find out whats causing this so i pressed F12 and searched the log:
