Error pulling data using extractionsContext.ExtractRaw

Hello, I have been running an extraction script for several weeks with no issue, but now I am getting an exception when I try to extract the data. I've attached the code and exception below. The exception occurs at this line:: RawExtractionResult extractionResult = extractionsContext.ExtractRaw(extractionRequest);

 TickHistoryTimeAndSalesExtractionRequest extractionRequest = new TickHistoryTimeAndSalesExtractionRequest {
                IdentifierList = InstrumentIdentifierList.Create(instrumentIdentifiers, instrumentOptions, false),
                Condition = reportTemplate.Condition,
                ContentFieldNames = { "Trade - Price", "Trade - Volume", "Quote - Bid Price", "Quote - Bid Size", "Quote - Ask Price", "Quote - Ask Size" }
            };


            extractionsContext.Options.AutomaticDecompression = false; //do not decompress
            //extractionsContext.InstrumentListOperations.ValidateIdentifiersWithOptions()


            Console.WriteLine("Beginning TRTH Extraction.");
            RawExtractionResult extractionResult = extractionsContext.ExtractRaw(extractionRequest);

@helen.ristov, there is currently an issue with the TRTH servers that sometimes return location URLs that are in HTTP instead of HTTPS.

Workarounds for C# are described in the last 2 responses for this query (see response by Jirapongse dated 4 Aug, and response by Veton Alia of today).
