c# - Asp.Net core "remember me" persistent cookie not works after deploy

Question

I've built an MVC Core (Framework) application and I use Identity to login. When I click "Remember me" option all is ok on my develop machine, but after deploy on server machine, "remember me" doesn't maintain login after 30 minutes.

I tried to check if cookie expiry date is set and seems to be ok, also on server machine the cookie seems well set. You can see my cookies detail in following image:

Can anyone help me to solve this issue?

Thanks in advance for your reply :)

EDIT:

As required by Orhun, I add below my Startup.cs content:

    public SymmetricSecurityKey signingKey;

            .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);

        if (env.IsDevelopment())
        {
            // For more details on using the user secret store see https://go.microsoft.com/fwlink/?LinkID=532709

        Configuration = builder.Build();
    }

I faced same issue. I couldn't solve it for a long time. But few days ago I found solution. As you mentioned in comments the problem is machine key. I don't know why, but application generates new machine key every time when it has been restarted. So way to solve problem is to force application to use constant key. To do it you need to add code like this in startup:

        public void ConfigureServices(IServiceCollection services)
        {

            var environment = services.BuildServiceProvider().GetRequiredService<IHostingEnvironment>();


            services.AddDataProtection()
                    .SetApplicationName($"my-app-{environment.EnvironmentName}")
                    .PersistKeysToFileSystem(new DirectoryInfo($@"{environment.ContentRootPath}keys"));

           ...

        }

After application's start in "key" folder you will find xml which contains your machine key. More details you can find here
