You can resolve this error by changing the web.config file.

If you are using ASP.NET 4.X, add the following lines to your web.config:
 
<system.serviceModel> 
     <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 
</system.serviceModel>
 
If you are using ASP.NET 2.0/3.0/3.5, add the following lines to your web.config:
 
<system.serviceModel> 
     <serviceHostingEnvironment> 
          <baseAddressPrefixFilters> 
               <add prefix="http://www.HostingAccountDomain.com"/> 
          </baseAddressPrefixFilters> 
     </serviceHostingEnvironment> 
</system.serviceModel>
