An error occurred while receiving the HTTP response WCF

I have a Windows app connecting to a WCF service that uses Entity Framework and is hosted in IIS. I get this error message when I try to return result of method in WCF service to my windows app:
An error occurred while receiving the HTTP response to http://localhost/BuyAndRechargeWcfService/BuyAndRechargeService.svc. > This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
Here is my web.config file of the WCF service:

When I try to debug the code I reach the return value of HandleCustomer method in WCF service and then I can't complete debugging (can't move to other statement the arrows is been disabled).
Please tell me if you want to provide you in any other parts of code

If possible, please check whether there is a record of 0 in the data found in the database.
When read in a program, it is converted to the corresponding enumeration type (enum), which does not define the enumeration value corresponding to 0. In this case, the conversion to an enumeration type does not throw an exception, and the value of the property remains 0 after the conversion. But when it is returned to the WCF client, the above exception is thrown.
The solution is to define the enumerated value corresponding to 0 in the enumerated type.

How to Solve DTD is prohibited in this xml document in WCF while connecting with Xamarin forms

I'm trying to connect my WCF service in Xamarine Forms, but in runtime I am getting this error
For security reasons DTD is prohibited in this XML document. To enable DTD processing set the DtdProcessing property on XmlReaderSettings to Parse and pass the settings into XmlReader.Create method.

Can anyone please tell me where I have to do changes to resolve this error?

This error has nothing to do with the wcf service. As the message says, set the DtdProcessing property on XmlReaderSettings to Parse and pass the settings to the XmlReader.Create method. You can refer to the code below.
https://learn.microsoft.com/en-us/dotnet/api/system.xml.xmlreadersettings.dtdprocessing?view=net-6.0
using System;
using System.Xml;
using System.Xml.Schema;

XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Parse;
settings.ValidationType = ValidationType.DTD;
settings.ValidationEventHandler += new ValidationEventHandler (ValidationCallBack);
// Create the XmlReader object.
XmlReader reader = XmlReader.Create("itemDTD.xml", settings);
// Parse the file.
while (reader.Read());
}
// Display any validation errors.
private static void ValidationCallBack(object sender, ValidationEventArgs e) {

EmpId is unique id for every employee. I am getting the details from Sql Server database. For testing i have sent 2 rows manually.
In android app for WebGet i have used :

urlToRequest.openConnection();
int statusCode = urlConnection.getResponseCode();

}
InputStream in = new BufferedInputStream(

String ss=getResponseText(in);
return new JSONObject(ss);
} catch (MalformedURLException e) {
// URL is invalid

// data retrieval or connection timed out

} catch (JSONException e) {
// response body is no valid JSON string
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
return null;
}
But i don't know how to POST with EmpId and getDataRows.
I have to consume this service in android app. I am using HttpURLConnection.
How to post using HttpURLConnection and getDatarows (json format) ?

You can use OutputStreamWriter as :
public static JSONObject PostWebService(String serviceUrl) {
HttpURLConnection urlConnection = null;
try {
// create connection
URL urlToRequest = new URL(serviceUrl);
urlConnection = (HttpURLConnection)
urlToRequest.openConnection();
urlConnection.setRequestMethod("POST");
urlConnection.setDoInput(true);
urlConnection.setDoOutput(true);
urlConnection.setRequestProperty("Content-Type", "application/json");
OutputStreamWriter out = new OutputStreamWriter(urlConnection.getOutputStream());
out.write("EmpID2016");
// You can write json also // Uncomment
// JSONObject jsonParam = new JSONObject();
// jsonParam.put("EmpID", "25");
// jsonParam.put("description", "Employer");
// jsonParam.put("authorized", "true");
// out.write(jsonParam.toString());
out.close();
int statusCode = urlConnection.getResponseCode();
if (statusCode == HttpURLConnection.HTTP_UNAUTHORIZED) {
// handle unauthorized (if service requires user login)
} else if (statusCode != HttpURLConnection.HTTP_OK) {
// handle any other errors, like 404, 500,..
}
// create JSON object from content
InputStream in = new BufferedInputStream(
urlConnection.getInputStream());
String ss=getResponseText(in);
return new JSONObject(ss);
} catch (MalformedURLException e) {
} catch (SocketTimeoutException e) {
} catch (IOException e) {
} catch (JSONException e) {
// response body is no valid JSON string
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
return null;

WCF restFULL service Deployed on Remote webserver throws error Unable to connect to the remote Server

I have developed WCF RestFul service and created GET and POST methods.

WCF REST POST base64 encrypted string

I have a WCF REST service that is reciving (POST) a string of base64 encoded json data. When I test this in fiddler2 I get a 400 bad request error
The problem seems to be with the lenght of the posted string but I don't get it cos in the web config I set the buffers and stuff to values that should be enugh. I don't know mybe the fiddlers buffer not enough but this would be odd I guess
In my testing I found out that the service actually fires if the request is a bit shorter then the actual full encoded object So I guess it has someting to do with the buffer but I fail to see the problem.
I got the encoded object back from the service as a get and tryed to put it back so the object is encoded correctly
Hope someone can help find the solution cos I think it is come detail I missed.
