.net Core Ubuntu HttpWebRequest错误：无此类设备或地址

Question

在我的.net核心项目中，我正在执行标准的Web请求（HttpWebRequest）。 将.net core 2.0更新到2.2后，它开始在ubuntu（docker）上产生错误。 在Windows环境下工作。

错误消息是：没有这样的设备或地址

代码：

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("SOAPAction", action);
webRequest.ContentType = "text/xml;charset=\"UTF-8\"";
webRequest.Accept = "text/xml";
webRequest.Method = "POST";

var soapBodyString = CustomXmlSerializer.ToXml(request);
var soapEnvelopeXml = utils.CreateSoapEnvolope<TRequest>(soapBodyString, 
typeof(TRequest), ref soapMethodFullName,  options);
InsertSoapEnvelopeIntoWebRequest(soapEnvelopeXml, webRequest);

var response = await webRequest.GetResponseAsync(); // Thrown error here
var responseStream = response.GetResponseStream();
var rd = new StreamReader(responseStream, Encoding.UTF8);
soapResult = rd.ReadToEnd();
