Why does ASP NET Core Identity constantly fail authorization?

Question

ASP.NET

Good day!
I've run into a problem that I can't find a solution to.
Log in to an ASP NET Core site using ASP NET Core Identity. Even after a few minutes of work, going to another page, authorization flies. You have to enter your username and password again.
At the same time, I look at cookies and .AspNetCore.Identity.Application is in place.
What could be the reason?

Answer 1

Although the cookies themselves are present, they have an expiration date. Pay attention to it, it may be too short.
