调用Web服务返回远程服务器返回错误：（502）错误的网关

Question

I am trying to call a web service in C# using WSDL proxy, the web service requires credentials to be passed

PartsInquiryServiceHttpService client = new PartsInquiryServiceHttpService();
        client.Url = "Url";
        client.Credentials = new NetworkCredential("user Name", "password");

In this line an exception is thrown

client.getMultiplePartsInquiry(enquiry);

unhandled exception of type 'System.Net.WebException' occurred in System.dll Additional information: The remote server returned an error: (502) Bad Gateway

Please help

Answer 1

The problem was in the Web.config. A proxy tag was added and the web service request fails because proxy credentials are not included. Simply removing the proxy section solved the problem.
