Implement Bearer Token Authentication in ASP.NET Core

I have an API secured by Bearer token to be consumed in a mvc project.

I'm using ClientFactory to call the API in mvc.

I get the generated token from WeatherForecast [HttpGet] method and use it to access the Authorized PlayerController methods.

It works fine in Postman, But when I try to access PlayerController in mvc, On running a debugger It shows Unauthorized response!

Here is the action to get and use the generated token in mvc project.

private async Task<JWTToken> CreateToken()
{
    var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost:42045/weatherforecast");
    var client = _clientFactory.CreateClient();
    HttpResponseMessage response = await client.SendAsync(request);
    var token = await response.Content.ReadAsStringAsync();
    HttpContext.Session.SetString("JwToken", token);
    return JsonConvert.DeserializeObject<JWTToken>(token);
 
}
public async Task<IActionResult> GetAllPlayers()
{
    JWTToken token = null;
    var strToken = HttpContext.Session.GetString("JwToken");
    if (string.IsNullOrWhiteSpace(strToken))
    {
        token = await CreateToken();
    }
    else
    {
        token = JsonConvert.DeserializeObject<JWTToken>(strToken);
    }
    if (token == null || string.IsNullOrWhiteSpace(token.token) || token.expireAt <= DateTime.UtcNow)
    {
        token = await CreateToken();
    }
    List<Player> players = new List<Player>();
    var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost:42045/api/player");
    var client = _clientFactory.CreateClient();
    request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token.token);
    HttpResponseMessage response = await client.SendAsync(request, HttpCompletionOption.ResponseHeadersRead);
    if (response.StatusCode == System.Net.HttpStatusCode.OK)
    {
        var apiString = await response.Content.ReadAsStringAsync();
        players = JsonConvert.DeserializeObject<List<Player>>(apiString);
 
    }
    return View(players);
}

Here is CreateToken method in WeatherForecast controller.

[HttpGet]
public ActionResult<string> Get()
{
    var rng = new Random();
    var weathers = Enumerable.Range(1, 5).Select(index => new WeatherForecast
    {
        Date = DateTime.Now.AddDays(index),
        TemperatureC = rng.Next(-20, 55),
        Summary = Summaries[rng.Next(Summaries.Length)]
    });
    return Ok(new {
        expireAt = DateTime.UtcNow.AddMinutes(15), token = CreateToken()
    });
}
public string CreateToken()
{
    var key = new SymmetricSecurityKey(System.Text.Encoding.ASCII.GetBytes(_configuration
        .GetSection("AppSettings:Token").Value));
    var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256Signature);
    var token = new JwtSecurityToken(
        claims: new List<Claim>
        {
            new Claim("firstName", "Ahmad"),
            new Claim("lastName", "Zooghii")
        },
        signingCredentials: creds,
        expires: DateTime.UtcNow.AddMinutes(15)
        );
    return new JwtSecurityTokenHandler().WriteToken(token);
}
