I have simplest WCF service (visual studio template one), which is working fine with http but fails with https. below is little detail.

Here is how it looks like in IIS.

Here is web.config

<system.serviceModel>
<services>
 <service name="WcfService1.Service1">
 <endpoint address="" binding="wsHttpBinding" contract="WcfService1.IService1" />
 <!--<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>-->
 </service>
</services>
<behaviors>
 <serviceBehaviors>
 <behavior>
 <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
 <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
 <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
 <serviceDebug includeExceptionDetailInFaults="false"/>
 </behavior>
 </serviceBehaviors>
</behaviors>
<protocolMapping>
 <add binding="basicHttpsBinding" scheme="https"/>
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>

Here is browser when I ping it from ip

here is browser when I ping it from domain name.

All good at this point. however when I tried to add a service reference in visual studio, it failed with https but successful with http.

this is ip one (http)

this is domain name one (https)

detailed error message is

The question I have here is why visual studio's cant get hold of https://tar.tennis.com.au/testwcf/service1.svc and is ok with http://10.21.100.129/testwcf/service1.svc ?

surely one is http and other is https but then why browser had no issues with it?

We need to add additional service endpoint for the support of https binding.
There are two ways to configure this, please refer to my example.
1. simplified configuration

 <system.serviceModel>
 <behaviors>
 <serviceBehaviors>
 <behavior>
 <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
 <serviceDebug includeExceptionDetailInFaults="false" />
 </behavior>
 </serviceBehaviors>
 </behaviors>
 <protocolMapping>
 <add binding="basicHttpBinding" scheme="http" />
 <add binding="basicHttpsBinding" scheme="https" />
 </protocolMapping>
 <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
 </system.serviceModel>

2. add the https service endpoint which uses the transport security.

<system.serviceModel>
 <services >
 <service name="WcfService1.Service1">
 <endpoint address="" binding="basicHttpBinding" contract="WcfService1.IService1"></endpoint>
 <endpoint address="" binding="basicHttpBinding" contract="WcfService1.IService1" bindingConfiguration="https"></endpoint>
 </service>
 </services>
 <behaviors>
 <serviceBehaviors>
 <behavior>
 <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
 <serviceDebug includeExceptionDetailInFaults="false" />
 </behavior>
 </serviceBehaviors>
 </behaviors>
 <bindings>
 <basicHttpBinding>
 <binding name="https">
 <security mode="Transport">
 <transport clientCredentialType="None"></transport>
 </security>
 </binding>
 </basicHttpBinding>
 </bindings>
 <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
 </system.serviceModel>

Feel free to let me know if there is anything I can help with.
