can anyone help on this

 

This is my cookiepolicyoption in Startup.cs

services.Configure<CookiePolicyOptions>(options => {
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => false;
options.MinimumSameSitePolicy = SameSiteMode.None;
});

This is the session configuration :-

services.AddSession(options => {
      options.IdleTimeout = TimeSpan.FromMinutes(30);
      options.Cookie.HttpOnly = true;
      options.Cookie.SameSite = Microsoft.AspNetCore.Http.SameSiteMode.Strict;
});
