با سلام و خسته نباشید

من توی پروژه ام از Jwt استفاده کردم و الان میخوام role base  احراز هویت انجام بشه . الان به تمام درخواست های که به سرور ارسال میشه پاسخ 401 داده میشه و میگه که دسترسی ندارید

لطفا بگید مشکل کجاست

کد های Startup

 services.AddAuthentication(cfg =>
            {
                cfg.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            })
            .AddCookie(CookieAuthenticationDefaults.AuthenticationScheme, cfg =>
            {
                // Cookie settings
                cfg.Cookie.HttpOnly = true;
                cfg.Cookie.Expiration = TimeSpan.FromDays(150);
                cfg.LoginPath = "/Account/Login"; // If the LoginPath is not set here, ASP.NET Core will default to /Account/Login
                cfg.LogoutPath = "/Account/Logout"; // If the LogoutPath is not set here, ASP.NET Core will default to /Account/Logout
                cfg.AccessDeniedPath = "/Account/AccessDenied"; // If the AccessDeniedPath is not set here, ASP.NET Core will default to /Account/AccessDenied
                cfg.SlidingExpiration = true;
            })
            .AddJwtBearer(JwtBearerDefaults.AuthenticationScheme, cfg =>
            {
                cfg.RequireHttpsMetadata = false;
                cfg.SaveToken = true;
                cfg.TokenValidationParameters = new TokenValidationParameters()
                {
                    ValidIssuer = ":Issuer",
                    ValidAudience = "Issuer",
                    IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("myKey"))
                };

            });

   و اینم کد تولید token 

  public async Task<ApiResponse> GenerateToken([FromBody] ApiLoginViewModel model)
        {
            ApiResponse apiResponse = new ApiResponse();
            if (!ModelState.IsValid)
            {
                apiResponse.Data = null;
                apiResponse.Response.Code = ResponseStateName.BadRequest;
                apiResponse.Response.Message = "Bad Request";
            }
            else
            {
                var user = _userManager.FindByEmailAsync(model.UserName).Result;
                if (user != null)
                {
                    var result = _signInManager.CheckPasswordSignInAsync(user, model.Password, false).Result;
                    if (result.Succeeded)
                    {
                        var claims =new List<Claim>()
                        {
                            new Claim(JwtRegisteredClaimNames.Sub, model.UserName),
                            new Claim(JwtRegisteredClaimNames.Jti, user.Id)
                        };
                        claims.AddRange((await _userManager.GetRolesAsync(user)).Select(r => new Claim(ClaimTypes.Role, r)));

                        var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("myKey"));
                        var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
                        var token = new JwtSecurityToken("Issuer", "Issuer", claims, expires: DateTime.Now.AddDays(30), signingCredentials: creds);
                        apiResponse.Data = new { token = new JwtSecurityTokenHandler().WriteToken(token) };
                        apiResponse.Response.Code = ResponseStateName.Ok;
                        apiResponse.Response.Message = "Ok";
                        return apiResponse;
                    }
                }
            }

            apiResponse.Data = null;
            apiResponse.Response.Code = ResponseStateName.SystemError;
            apiResponse.Response.Message = "Con Not Create Token";
            return apiResponse;
        }

میخوام به صورت زیر استفاده کنم ولی جواب نمیده
