Я использую SendgridAPI для отправки пользователю электронного письма с подтверждением. Я создаю API_key в приложении sendgrid (https://app.sendgrid.com) и устанавливаю его api в свой проект.

мой код выполнения в c# выглядит следующим образом: 

public static async Task<bool> Execute(string userEmail, string userName, string plainTextContent, string htmlContent, string subject)
        {
            var apiKey = "SG.E43545453453URY1A.tq8j-fduDHDKONPuf_Gp1W35IkQjI-DzRsAsmgdfdfg5DgEBM";
            var client = new SendGridClient(apiKey);
            var from = new EmailAddress("test@example.com", "Mehran");
            var to = new EmailAddress(userEmail, userName);
            var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);
            var response = await client.SendEmailAsync(msg);
            return await Task.FromResult(true);
        }

и я называю этот метод. при запуске приложения и этого метода генерировать исключение ниже:
