System.ArgumentOutOfRangeException при обновлении соединения WebSocket? ⇐ C#

[Anonymous]

Я пытаюсь преобразовать игровой сервер с TCP на WebSockets. С TCP все работало нормально, но после реализации механизма протокола переключения для поддержки веб-сокетов я теперь получаю исключение при декодировании сообщения.
Я получаю исключение:
System.ArgumentOutOfRangeException: count ('-2103261134') must be a non-negative value. (Parameter 'count') Actual value was -2103261134.

Вот единственный код, который я добавил, внутри частной асинхронной задачи OnReceivedAsync(int bytesReceived), которая вызывается при получении байтов.
var stringData = Encoding.UTF8.GetString(data);

if (stringData.Length >= 3 && Regex.IsMatch(stringData, "^GET"))
{
await UpgradeConnectionAsync(stringData);
return;
}

Метод UpgradeConnectionAsync:
private async Task UpgradeConnectionAsync(string data)
{
const string eol = "\r\n"; // HTTP/1.1 defines the sequence CR LF as the end-of-line marker

var response = Encoding.UTF8.GetBytes("HTTP/1.1 101 Switching Protocols" + eol
+ "Connection: Upgrade" + eol
+ "Upgrade: websocket" + eol
+ "Sec-WebSocket-Accept: " + Convert.ToBase64String(
System.Security.Cryptography.SHA1.Create().ComputeHash(
Encoding.UTF8.GetBytes(
new Regex("Sec-WebSocket-Key: (.*)").Match(data).Groups[1].Value.Trim() + "258EAFA5-E914-47DA-95CA-C5AB0DC85B11"
)
)
) + eol
+ eol);

await _networkClient.WriteToStreamAsync(response);
}

Сообщения, которые клиент отправляет на сервер (инструменты разработки Chrome, UTF8):
