Network service error (Assassin's Creed: Origins)

yesterday faced with such a problem, searched in the e-day, solutions and did not find, maybe who faced? For two months the game worked fine, but yesterday suddenly broke this one!!!! I can't see the custom screens, and the store doesn't ship!!!
There was an error when you connected to Ubisoft's network service.
