WebClient请求期间发生异常 C＃

如何解决WebClient请求期间发生异常 C＃

我正在尝试从下面的代码下载dll并将其注入csgo，但我一直收到此错误“在WebClient请求期间发生异常”。我的dll的下载网站正确无误，并且文件路径也正确。但是我对导致它的原因不了解。

注入代码

{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender,EventArgs e)
        {
            var name = "csgo";
            var target = Process.GetProcessesByName(name).FirstOrDefault();

            if (target != null) // if csgo is running 
            {
                WebClient download = new WebClient();
                download.DownloadFile(settings.dllonsite,settings.dllondevice); //download the dll

                if (!File.Exists(settings.dllondevice)) //check if the dll exists
                {
                    MessageBox.Show(settings.unexpectedmsg,settings.cheatname);
                    Application.Restart();
                }
                var dll = File.ReadAllBytes(settings.dllondevice);
                var injector = new ManualMapInjector(target) { AsyncInjection = true };
                label1.Text = $"hmodule = 0x{injector.Inject(dll).ToInt64():x8}"; //inject the dll into the target

                File.Delete(settings.dllondevice); //delete the dll
            }
            else
            {
                MessageBox.Show(settings.csgomsg,settings.cheatname); //csgo is not running
            }

        }

        private void Form2_Load(object sender,EventArgs e)
        {
            listBox1.Items.Add("CSGO"); //0 you can add more if you want
        }

        private void listBox1_SelectedindexChanged(object sender,EventArgs e)
        {

        }
    }
}

要从数据库下载并检查数据库中的用户信息的站点代码。“ example.com”已替换为100％有效的我的域。我可以使用下载链接从它手动下载一切正常。
