ASP NET CORE身份突然注销

Question

我正在使用asp .net core 2.2和Identity Core。我不知道怎么了。当我想登录到管理面板时，我成功完成了，但是当我单击管理面板中的某些链接时，它突然注销了！我不知道为什么会这样。身份cookie突然变为空？到底是怎么回事？我的Web应用程序中没有错误。我的意思是浏览器中什么也没有显示。有时，当我登录时，我单击链接，但并不会突然注销，但有时却会注销。Cookie是否有问题？我会很感激任何帮助。在我的本地计算机上，一切正常，但是在服务器上我有此问题。 我将startup.cs放在这里，以便大家看到

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.

            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "areas",
                    template: "{area:exists}/{controller=Home}/{action=Index}/{id?}"
                );

                routes.MapRoute(

                );
            });

        }

这是我在管理区域中的控制器之一

   [Area("SFAdmin")]
    [Authorize(Roles = StaticDetails.AdminRole)]
    public class UsersController : Controller
    {
        public IActionResult Index()
        {
            return View();
        }
    }
