Problems with cookies

I log in with my google accoount, but every day I have to delete vaadin site cookies to log in again.
If not, when I click “log in” the page refresh, but I’m not logged in.

That’s strange. I’ve seen that behavior before (very haphazardly) with a simple email-address login, but usually clearing the cookies has fixed things with me. Have you tried to log in with some other browser for a while? Does that still happen to you then?

If i clear the cookies it works, but I have to clear 3-4 times a day…
Same behaviour with Chrome.
