google account disappeared

[Android Central Question]

i have several google accounts. and all of a sudden i don't see one of my accounts (actually, my main account) in the list of my accounts in several google services/applications on phone, like Keep, Drive, etc... at the same time other services on phone work well, like Gmail, Google+, Photos. I don't have any issues with my sign-in. I tried to remove and add account. nothing helped and nothing changed.any help?
