Uploading via service and getting message endpoint not available on larger sized files

I have a WCF service running on a virtual machine. I haven't changed anything on this server or the service in quite some time. When I try to send up a file through the service that is ~25 mb I am getting this:
----------------------------------------------------------

Message: There was no endpoint listening at http://www.myservice.com/xxx/FileService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

When I send up a smaller file, such as a 1mb file, I have no issues. I have tested this on several computers and I get the same results.
Any suggestions?

There are 3 things that you can change in order to make it work :
IIS Host Settings:
I believe you have hosted the WCF service in IIS. Hence you need to set the
When sending large amounts of data you will need to set the maxAllowedContentLength IIS setting (for more information see Configuring IIS Request Limits)
This value defaults to ~28MB as far as I know.
Max Received Message Size:
You will have to change this to some other value (e.g. long.MaxValue). By default it is set to 64 KB.
Enable Streaming
By default the mode of transmission for WCF is buffered. While sending and receiving all data need to be present in memory - which would not be possible for large files.
Hence you will have to change the mode to "streaming" as shown below:
<system.serviceModel>
…
<bindings>
<basicHttpBinding>
<binding name="ExampleBinding" transferMode="Streaming"/>
</basicHttpBinding>
</bindings>
…
<system.serviceModel>
Refer the documentation.

WCF communication error

We've been encountering a WCF communication error for a couple of days now and I can't figure out what is causing the error. I originally thought that it was an SSL cert issue, but it's not. I also made sure the endpoint was reachable by just entering the URL on the web browser and it is view-able. I also made sure that the default request size is not causing the problem. I'm certain that the requests are less than the default of 30MB.
What other things can prevent this stack trace error?

Try to set KeepAlive off.
Something like:

var customBinding = new CustomBinding(client.Endpoint.Binding);
var transportElement = customBinding.Elements.Find<HttpTransportBindingElement>();
transportElement.KeepAliveEnabled = false;
client.Endpoint.Binding = customBinding;

You should use Trace Viewer Tool (SvcTraceViewer.exe) to find out server error

I had similar errors coming from the depths of my http bindings in WCF.
client -> The underlying connection was closed: An unexpected error occurred on a receive.
client -> Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
server (got this with the help of "procdump") -> The I/O operation has been aborted because of either a thread exit or an application request
Eventually after many hours I came upon the HTTP.sys logging (in C:\WINDOWS\System32\LogFiles\HTTPERR ) and I discovered that the WCF self-hosted service connections were being forcibly dropped (on purpose) because of an obscure configuration issue (minimum send rate bytes per second). Unfortunately it took another few hours to reconfigure that (you cannot do it via "netsh http add timeout" so you have to do it within the app or within IIS when not self-hosted).

I dont't know if is the same error, but in my case, the exception was in Json, that cannot convert the Date value, because it was empty.
DateTime values that are greater than DateTime.MaxValue or smaller than DateTime.MinValue when converted to UTC cannot be serialized to JSON.
The trace viewer was very useful to find the issue.

Configure WCF tracing in your app.config / web.config and check Error.svclog (it will be created near your binary file) for details.
In my case it was because of using Auto-property initializer (property without setter) - a feature from C# 6.0

I am sure that my web service is retrieving data from DB. but is unable to transfer to my web from where i initiated the call. Thanks in advance for any help.

I had recently the same problem with a Wcf service within a .Net 4.0 web app. I increased the maxItemsInObjectGraph value and server didn't throw the exception anymore. The documentation here says the default maximum is Int32.MaxValue but I think it is incorrect, the maximum value is 65535.
<serviceBehaviors>
<behavior name="ServiceBehaviour">
<dataContractSerializer maxItemsInObjectGraph="6553500"/>
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>

The other thing you can do is enable tracing. This is an example of what I have in the web.config:
<system.diagnostics>
<sources>
<source name="System.ServiceModel"
switchValue="Information, ActivityTracing"
propagateActivity="true">
<listeners>
<add name="traceListener"
type="System.Diagnostics.XmlWriterTraceListener"
initializeData= "c:\temp\log\Traces.svclog" />
</listeners>
</source>
</sources>
</system.diagnostics>
If you double click on the Traces.svclog, windows should open the Microsoft Service Trace Viewer.
If you test your service with the Microsoft WCF Test Client make sure you change the default client config to match the server settings (this includes the client endpoint behavior) to make sure the client can receive the response from the server.

Make your client basicHttpBinding the same as your server binding. This is a verry common error to only change one binding instead of server and client binding.
If that not works you can enable wcf tracing:
wcf tracing
That will give you more insights in what the underling problem is.

Add following configuration to your wcf service config. And see c:\log\Traces.svclog file.
My exception was throw for ;
There was an error while trying to serialize parameter
The InnerException message was 'Enum value '0' is invalid for type 'ThyCams2014.XrmBase.new_filingstatu' and cannot be serialized. Ensure that the necessary enum values are present and are marked with EnumMemberAttribute attribute if the type has DataContractAttribute attrienter code herebute.'. Please see InnerException for more details.
<configuration>
<system.diagnostics>
<sources>
<source name="System.ServiceModel"
switchValue="Information, ActivityTracing"

<listeners>

initializeData= "c:\log\Traces.svclog" />
</listeners>
</source>
</sources>
</system.diagnostics>
</configuration>

This statement solved my problem:
db.ContextConfiguration.ProxyCreationEnabled = false;

we had a loop in our object graph that were returning. I know this probably isn't your problem but I'm adding it here in case anyone else has the same problem. We had includeExceptionDetailInFaults enabled but weren't getting the error in any client (our application or the WCF Test Client). Luckily it showed up in server logs so we were able to find it that way.
We had Parent -> child and child -> parent for two-way navigation, we had to break that link and instead have parent -> child, and the child had an id to lookup the parent, then the error went away.

Had the same error after migrating to a new server.
It finally boiled down to a missing targetFramework attribute that was not needed on the old server...
<system.web>
<httpRuntime enableVersionHeader="false" targetFramework="4.7.2"/>
</system.web>

Application Scenario : Client is getting data from server through WCF service and using nettcp binding. Server is connected with real device and generating 20-30 events every seconds. Generated events are pushed as string message to all connected clients using callback interface of WCF. It's working fine if client have no any process load (just receive event and display). But it gives error when we do some loading process at client side and busy for some time.
Note: I had already set maximum all timeouts in nettcp binding as below, but still problem not solved.
NetTcpBinding tcpBinding = new NetTcpBinding(SecurityMode.None);
tcpBinding.MaxBufferPoolSize = 2147483647;
tcpBinding.MaxReceivedMessageSize = 2147483647;

tcpBinding.SendTimeout = TimeSpan.MaxValue;

Please guide me is there any other settings required related to communication channel or binding ?

As you mentioned in your question, you have set all timeouts to maximum. So as per my opinion, there should be problem in InstanceContextMode you defined. Which mode you defined in your service ? PerSession, PerCall or Single. There might be PerCall you defined and calling service by same object (globally declared object of service) then it's possible to channel come in fault state or connection disconnected.
So If you defined PerSession mode then use single object (Globally declared) from client side to get data from service. If you defined PerCall option then create new object every time.
Hope this help to you. Please feel free to ask any doubt...
