I hosted my wcf using iis 7.0, the url is:

```
https://example.com/CustPortal/CustomerService.svc

```

when i add service reference in vs2008, got this errors:

```
The document at the url https://example.com/CustPortal/CustomerService.svc was not recognized as a known document type.
The error message from each known type may help you fix the problem:
- Report from 'DISCO Document' is 'There was an error downloading 'https://el-cust-port01/CustPortal/CustomerService.svc?disco'.'.
  - Unable to connect to the remote server
  - No connection could be made because the target machine actively refused it 59.37.71.86:443
- Report from 'WSDL Document' is 'The document format is not recognized (the content type is 'text/html; charset=UTF-8').'.

- Report from 'XML Schema' is 'The document format is not recognized (the content type is 'text/html; charset=UTF-8').'.

Metadata contains a reference that cannot be resolved: 'https://193.91.152.191/CustPortal/CustomerService.svc'.

My web.config is
