Answer 1

I found several problems with your code:
1.The metadata exchange (mex) endpoint should be:

 <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> 

2.You are using https protocol, so you need to set httpsGetEnabled to true.

  <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/> 

3.You are using webHttpBinding, but <protocolMapping> is using basicHttpBinding.
4.HTTPS is transport authentication, so you need to set:

<security mode="Transport">

5.Make sure your service is running.
