HttpClient получил ошибку при использовании метода ChooseSslConnectionAsync в методе SendAsync ⇐ C#

[Anonymous]

У меня есть ApiAdapter с использованием HttpClient для отправки HTTP-запросов на мой сервер.
Чтобы избежать создания множества HttpClient, я использую DependenceInjection с одноэлементным режимом для класса «ApiAdapter». он работает хорошо, когда я вызываю только один HTTP-запрос.
Я хочу использовать Parallel.ForEachAsync, чтобы сократить время производительности, потому что я хочу создать 1000 человек через ApiAdapter.
Он выдает исключение с ошибкой сообщения ниже после создания ~ 30–100 человек
с сообщением:

Вот мой код
public async Task RequestPerson()
{
var threadRequestPins = Enumerable.Range(0, listSize).ToList();
await Parallel.ForEachAsync(datasToProcess, async (_, token) =>{
var fakfurTestApiService = LoadTestKernel.Kernel.Get();
var personCreated = await fakfurTestApiService.CallPostRequestAsync(, );
//CallPostRequestAsync will call ApiAdapter with PostRequestAsync() method below
});
}

//constructor
public ApiAdapter()
{
_cookieContainer = new CookieContainer();
_httpClientHandler = new HttpClientHandler
{
CookieContainer = _cookieContainer
};
_httpClient = new HttpClient(_httpClientHandler);
}

private void AddCertificates()
{
if (_certificate2Collection != null )
{
_httpClientHandler.ClientCertificates.AddRange(_certificate2Collection);
}
}

public async Task PostRequestAsync(string testApiRelativeUrl, TBodyRequest bodyRequest,
CancellationToken cancellationToken = default) where TResult : class
{
var uriBuilder = BuildRequestUri(testApiRelativeUrl);
var request = new HttpRequestMessage(HttpMethod.Post, uriBuilder.Uri);
AddCertificate(request);
request.Content = new StringContent(_jsonSerializer.SerializeObject(bodyRequest), Encoding.UTF8,;
var response = await _httpClient.SendAsync(request, cancellationToken);
return await ExtractBodyFromResponseAsync(response);
}
