Amazon ECS API spontaneous "(400) Bad Request" errors for ItemSearch() - c#

Starting at about 11 PM CST on 5/29/2017, I began receiving "(400) Bad Request" errors for all my ItemSearch() calls. I am using the C# API and have been doing so successfully for well over a year now with no problems. No code or configuration has changed on my end, and I have been able to reproduce the error both in production and development. My security credentials appear to still be valid according to the IAM Management Console, and I haven't received any communications from Amazon that would indicate that my account has been deactivated or anything of that nature.
This is what is returned for all of my calls:
System.ServiceModel.ProtocolException: The remote server returned an unexpected response: (400) Bad Request. ---> System.Net.WebException: The remote server returned an error: (400) Bad Request.

Is anyone else experiencing this?
I did check this very old thread, but I don't believe it's relevant given how this sprung up out of nowhere and has been working perfectly for so long.

TransactionAutoComplete set to false cannot be used with operations on callback contracts

A normal HTTP WCF Service is throwing this error when trying to connect to a legacy NetTCP binding. I want to be able to flow the transaction to the service and have that enabled. I am not using a duplex contract so why is it even mentioning a 'callback' contract in the error message?
Please just say if you need to see some more code, but I'll take any suggestions right now!
** the error is thrown when it's doing a ChannelFactory.CreateChannel()
The operation 'XService' on callback contract 'IXService' is configured with TransactionAutoComplete set to false. TransactionAutoComplete set to false cannot be used with operations on callback contracts.

I had the same problem.
I was starting a service programmaticaly all along with the configuration (base address, binding, endpoint,...).
I ended up exporting all configuration to the config file and it worked.

UNC FileShare Authentication for WCF Web Service?

We have a WCF Service which will Upload and Download Documents to and from FileShare respectively.
The client application will pass a FileShareLocation and FileName inthe request.
But we are getting some exception, and not able to get the response.
FileSharePath sample : \\SERVERIP\SHAREDFOLDER
Note: The service is working fine when I don't use Network File Share.

Although increasing the timeout on both ends of the wire (BTS and WCF Service) may help avoid the error in some instances, you might just be kicking the can further down the road and you probably need to get to the root cause (does this specific web service call NORMALLY take over 20 seconds to complete?).
It is likely that under high load, or low capacity conditions, that your WCF Web Service cannot keep up with the rate of messages that BizTalk is able to send to it.
Depending on what your WCF Service does, you might look at optimising:
Database
SQL blocking while waiting for locks
DB performance may reduced during admin tasks such as Reindexing Jobs, Backups etc
IIS / ASP.NET
See if requests are being queued
Look at any throttling on the WCF Service side (e.g. MaxConcurrentCalls)
If there is no chance of further optimisation (or scale up / out) on the WCF Service side, you may need to look at throttling the number of concurrent orchestrations (using a variant of a Singleton Orch) or limiting the number of threads on your WCF Send Port Adapter (unfortunately, this will affect all messages, so you might need to split out separate SendHost
Be wary when simply 'maxing out' all of the WCF knobs - settings like maxReceivedMessageSize (or maxBufferSize) ="2147483647" will often result in OutOfMemoryExceptions and / or increase the threat surface area.
You need to change the timeout of the WCF service.
I am not sure if that solution is correct, but it is definitely in the web.config file.
I had similar problem when using SOAP adapter(I'm still in biztalk 2006)
You should try the following :
YourMessage(SOAP.ClientConnectionTimeout) = 900000;
900000 is the default value, so increase it to fit your need, the time is in milliseconds.
If this property does not apply to WCF web services, I assume there is a WCF equivalent for that property.

Sharepoint 2010 problems with WCF service

I need to create wcf service for sharepoint 2010. The idea to use Jquery ajax to communicate with this service. But all cals to service methods always fail.
The
I try to use WCF Test Client and get message:
Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.
and error detais:
The content type text/html; charset=utf-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 227 bytes of the response were: 'A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - Either a required impersonation level was not provided, or the provided impersonation level is invalid.)'.

Everything done according to article on msdn
http://msdn.microsoft.com/en-us/library/ff521581.aspx
Whats the problem and how to deal with it?
Evgeny:
It looks like your webservice returns standard SOAP XML response. JQuery expects to use JSON. I think the easier way is to set JQuery to use XML. Alternatively you can change your web service to return JSON instead of XML.
Solution: Anonymous access have to be enabled!

TimoutException occurs over a network but not locally

I have a program with three WCF services and when I run them locally (i.e: Server and Clients are all on localhost) everything works. However when I test them across a network I get a TimoutException on two services but not the other. I've disabled the firewalls on all the machines involved in the test. I can both ping the server and access the wsdl "You have created a service" webpage from the client
The service that works uses a BasicHttpBinding with streaming and the two which don't work use WSDualHttpBinding. The Services that use WSDualHttpBinding both have CallbackContracts. I apologise for the vagueness of this question but I'm not really sure what code to include or where to even start looking for the solution to this.
Non-working bindings:
public static Binding CreateHTTPBinding()
{
var binding = new WSDualHttpBinding();
binding.MessageEncoding = WSMessageEncoding.Mtom;
binding.MaxBufferPoolSize = 2147483647;
binding.MaxReceivedMessageSize = 2147483647;
binding.Security.Mode = WSDualHttpSecurityMode.None;
return binding;
}

You are using a DualHttpBinding. What this means is that you are setting up a duplex channel, where server can send messages (not response message, but a incoming message) to client. But you haven't setup a clientBaseAddress where client will be listening for incoming messages from server. This is what is causing this issue. from http://msdn.microsoft.com/en-us/library/system.servicemodel.wsdualhttpbinding.aspx:
This binding requires that the client has a public URI that provides a callback endpoint for the service. This is provided by the ClientBaseAddress. A dual binding exposes the IP address of the client to the service. The client should use security to ensure that it only connects to services it trusts.
