I have a website that has been working for a while. Once I log in, it keeps me logged in for several weeks.

However, I’ve just moved to a new server. And now, every time I’m away from the computer for hours, I have to log in again.

Does anyone know what could cause this?

Below is my configuration code.

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseMigrationsEndPoint();
    }
    else
    {
        app.UseExceptionHandler("/Error");
        app.UseStatusCodePagesWithReExecute("/ErrorCode", "?code={0}");
        // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
        app.UseHsts();
    }

    if (IsDemoSite)
    {
        app.UseHttpsRedirection();
    }
    else
    {
        RewriteOptions options = new RewriteOptions()
            .AddRedirectToHttpsPermanent()
            .AddRedirectToWwwPermanent();
        app.UseRewriter(options);
    }

    app.UseStaticFiles();

    app.UseRouting();

    app.UseAuthentication();
    app.UseAuthorization();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers(); // For Railtrax API
        endpoints.MapRazorPages();
    });
}
