the resource cannot be found wcf service with SSL - asp.net

Question

I created a REST api using asp.net vb and I was trying to invoke the api through secure connection (https) but I had an error
The resource cannot be found
I can invoke any method using (http), but with (https) I can't. And I can access the main page of api (service.svc) using the (https) but the problem with functions!! below are my config and function header.
<system.serviceModel>
<services>
<service name="RESTAPI" behaviorConfiguration="MyServiceTypeBehaviors">
<endpoint address="customBinding" binding="customBinding" bindingConfiguration="basicConfig" contract="RESTAPI"/>
<endpoint address="" behaviorConfiguration="HerbalAPIAspNetAjaxBehavior"
binding="webHttpBinding" contract="HerbalAPI" />
<endpoint contract="RESTAPI" binding="mexHttpBinding" address="mex" />
</service>
</services>
<!-- **** Services ****-->

You need to define a special binding configuration in your web.config file to allow the SVC service to bind correctly for HTTPS requests.
Please have a look at this blog post: https://weblogs.asp.net/srkirkland/wcf-bindings-needed-for-https
Your service will already be defined in the web.config, just add the bindingConfiguration attribute:
<services>
<service name="TestService">
<endpoint address="" behaviorConfiguration="TestServiceAspNetAjaxBehavior"
binding="webHttpBinding" bindingConfiguration="webBindingHttps" contract="TestService" />
</service>
</services>
Then define the special binding settings for the webHttpBinding as so, the magic part that fixes the HTTPS request is the <security mode="Transport" />:
<bindings>
<webHttpBinding>
<binding name="webBindingHttps">
<security mode="Transport">
</security>
</binding>
</webHttpBinding>
</bindings>
This will effectively switch the service over to HTTPS, but if you want to have both HTTP and HTTPS to work you need to define 2 binding configurations and then have 2 identical endpoints per service, where the one uses the http bindingConfiguration and the other uses the https bindingConfiguration like so:
<bindings>
<webHttpBinding>
<binding name="webBindingHttps">
<security mode="Transport">
</security>
</binding>
<binding name="webBindingHttp">
<!-- Nothing special here -->
</binding>
</webHttpBinding>
</bindings>
<services>
<service name="TestService">
<endpoint address="" behaviorConfiguration="TestServiceAspNetAjaxBehavior"
binding="webHttpBinding" bindingConfiguration="webBindingHttps" contract="TestService" />
<endpoint address="" behaviorConfiguration="TestServiceAspNetAjaxBehavior"
binding="webHttpBinding" bindingConfiguration="webBindingHttp" contract="TestService" />
</service>
</services>
