How do I use proxy settings for zscalar in C#? My program is as follows:

My program is as follows:

var ExtractionsContext = new ExtractionsContext(new Uri("https://hosted.datascopeapi.reuters.com/RestApi/v1/"), "[username]", "[password]");
var proxy = new WebProxy("http://Zscaler-lb.apac.zzzz.corp:80", true);
ExtractionsContext.Options.UseProxy = true;
ExtractionsContext.Options.Proxy = proxy;
var availableFields = ExtractionsContext.GetValidContentFieldTypes(ReportTemplateTypes.TickHistoryTimeAndSales);

However when I run the program, I am getting the following error:

An exception of type 'ThomsonReuters.Dss.Api.InvalidResponseException' occurred in mscorlib.dll but was not handled in user code
Additional information: Invalid response, could not parse the following response:

Hi @vivek.arkalgud,

From the error provided, it seems that DataScope Select .NET SDK received a "Welcome To Zscaler Directory Authentication" page from Zscaler as a response instead. So the SDK cannot handle the response and log the error.

Please contact Zscaler support or network administrator who manages Zscaler in your environment to investigate this issue further. Also, does Zscaler require any credential for access?

Finally I managed to get it working. We have to add reuters.com url to the SSL inspection. That resolved the problem.
