Unable to connect to the remote server when submitting a Batch Job

[uvsuperDev]

Hi guys!

We get "Unable to connect to the remote server" error when submitting a batch job request.
InnerException: System.Net.Sockets.SocketException (0x80004005): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 172.217.7.240:443 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception)

It started a day ago. 

Any insights?

Any issues with the remote server?

Hi,

Are you facing these issues repetitively? Did any change happen recently to your network/proxy configuration? Issues like these are sometimes intermittent and tend to go away after a few retries. If you happen to see this error again, please let me know.

Hello sirs, 

I am having the same issue. BTW, I received it in the first time I tried. I am using a hosting provider and they require to define a proxy address of theirs in order to make web services out. 

Everything works in my local. 

In hosting environment, the service that I use to get Accounts works as expected.  I use get method of  (ManagedCustomerService)user.GetService(AdWordsService.v201806.ManagedCustomerService)) in .NET. 

Once the code requested the report. it waits for a few minutes then returns below error. I use CRITERIA_PERFORMANCE_REPORT with .net library. 

The shortened version of my code is below:

            ReportDefinition definition = new ReportDefinition()

            {

                reportName = "Last 1 days CRITERIA_PERFORMANCE_REPORT",

                reportType = ReportDefinitionReportType.CAMPAIGN_PERFORMANCE_REPORT,

                downloadFormat = DownloadFormat.CSV,

                dateRangeType = ReportDefinitionDateRangeType.YESTERDAY,

                selector = new Selector()

                {

                    fields = new string[]

               {

                        "CampaignId",

                        "ExternalCustomerId",

                        "Cost",

                        "Date"

               },

                }

            };

            ReportUtilities utilities = new ReportUtilities(user, "v201806", definition);

           ReportResponse response = utilities.GetResponse()

Message:A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 108.177.15.138:443, StackTrace:   at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)\r\n   at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception) }"

Do you have any suggestion for this? Please let me know if I can provide any more details. 

Thank you very much for your support.

Hello Alperen,

The issue seems to be specific to your environment setup. I found another thread about the same topic which might be useful for you. If the suggestions on that thread is not helpful for you, could you please open a new issue on the .NET client library? The library owner is better equipped to address this question.

Thanks,

Hi Sreelakshmi,

Thank you for your response. 

After your message, I checked the source code of adwords api.net client and I noticed the below line in BuildRequest method of HttpUtilities class

            request.Proxy = config.Proxy;

This line overrides the configuration which I included in web.config.

I assigned Proxy member of  AdWordsAppConfig object which I pass to the service like below line:

                config.Proxy = new System.Net.WebProxy(new Uri("proxy address here"), false) { UseDefaultCredentials = false, };

And it works now. 

Thank you very much for your support.
