WCF returning Endpoint not found on live

Question

I have hosted a WCF service on shared environment which contains two different methods. One is returning the desired output, while the other gives endpoint not found exception, which is my main method to authenticate users.

The scenario is depicted here:

My Iservice.cs is as below

[OperationContract]
[WebInvoke(Method="GET", UriTemplate = "Data?Id={id}", ResponseFormat=WebMessageFormat.Json)]
string GetData(string id);

[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "Login?InstId={inst}&UserId={user}&pwd={pwd}", ResponseFormat = WebMessageFormat.Json)]
string Authenticate(string inst, string user, string pwd);

which then authenticates user details through DAL, which is working fine. My web config is as below:

  <system.serviceModel>
    <!--<serviceHostingEnvironment multipleSiteBindingsEnabled="True" aspNetCompatibilityEnabled="True">
    </serviceHostingEnvironment>-->
    <serviceHostingEnvironment multipleSiteBindingsEnabled="True">
    </serviceHostingEnvironment>
    <services>
      <service name="WCFDemo.Service1">
        <endpoint address="http://www.ekotri.com/Service1.svc" behaviorConfiguration="restfulBehavior"
                  binding="webHttpBinding" listenUri="/" bindingConfiguration="" contract="WCFDemo.IService1">
        </endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://www.ekotri.com" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="restfulBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="restfulBehavior">
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

GetData is working fine, but Authenticate gives endpoint not found error. It works fine on local IIS though.

Try this configuration:

<system.serviceModel>
<!--<serviceHostingEnvironment multipleSiteBindingsEnabled="True" aspNetCompatibilityEnabled="True">
</serviceHostingEnvironment>-->
<serviceHostingEnvironment multipleSiteBindingsEnabled="True">
</serviceHostingEnvironment>
<services>
  <service name="WCFDemo.Service1">
    <endpoint address="rest" behaviorConfiguration="restfulBehavior"
              binding="webHttpBinding" contract="WCFDemo.IService1">
    </endpoint>
    <host>
      <baseAddresses>
        <add baseAddress="http://www.ekotri.com/Service1.svc" />
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <endpointBehaviors>
    <behavior name="restfulBehavior">
      <webHttp />
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="restfulBehavior">
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>

I have tested it on default WCF application project from visual studio and did not have any problems.

Try changing your interface like this

[OperationContract]
 [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "Login/{inst}/{user}/{pwd}",
    BodyStyle = WebMessageBodyStyle.Bare)]
string Authenticate(string inst, string user, string pwd);

Put this configuration,

<system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="customBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
      <security mode="None">
        <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
        <message clientCredentialType="UserName" algorithmSuite="Default"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<services>
  <service behaviorConfiguration="asmx" name="WCFDemo.Service1">
    <endpoint address="basic" binding="basicHttpBinding" name="httpEndPoint" contract="WCFDemo.IService1"/>
    <endpoint address="json" binding="webHttpBinding" behaviorConfiguration="webBehavior" name="webEndPoint" contract="WebApplication1.IService"/>
    <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
  </service>
</services>
<behaviors>
    <endpointBehaviors>
        <behavior name="webBehavior">
            <webHttp />
        </behavior>
    </endpointBehaviors>
    <serviceBehaviors>
    <behavior name="asmx">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>

Answer 3

What url are you using when you attempt to hit your login method?

According to your service file, the url template you are using is

Login?InstId={inst}&UserId={user}&pwd={pwd}

Further in your config file you are binding it to a specific domain/url path

<endpoint address="http://www.ekotri.com/Service1.svc" behaviorConfiguration="restfulBehavior"
                  binding="webHttpBinding" listenUri="/" bindingConfiguration="" contract="WCFDemo.IService1">

Based on these two pieces of information, the expected access path would be

http://www.ekotri.com/Service1.svc/Login?InstId={inst}&UserId={user}&pwd={pwd}

If I take that template url and plug in some fake values..

Service Action URL

This url returns "False" which is expected.
