推荐答案

亲爱的朋友，

您提供的凭据不正确，或与防火墙专家联系.他们为PROD服务器打开了防火墙，因此无需使用代理.
或

您必须在两个位置设置凭据才能克服407错误:

Dear Friend,

Either the credentials you are providing are incorrect or Check with your firewall expert. They open the firewall for PROD servers so there is no need to use the Proxy.
OR

You have to set the Credentials in two locations to get past the 407 error:

HttpWebRequest webRequest = WebRequest.Create(uirTradeStream) as HttpWebRequest;
webRequest.Proxy = WebRequest.DefaultWebProxy;
webRequest.Credentials = new NetworkCredential("user", "password", "domain");
webRequest.Proxy.Credentials = new NetworkCredential("user", "password", "domain")

检查StackOverFlow上的该线程是否有帮助.
需要407个代理身份验证 [

Check if this thread on StackOverFlow is of any help.
