Importing from web

Good day - Any suggestion on how to get around this?

The website I am trying to get data from is www.manheim.com. I have a log in credentials. I usually enter my logins when I open the import from web window.

No the import from web too tries to open a retired and non existing site:

: "Web.Contents failed to get contents from 'http://www.manheim.com/exporttrader

I hope you can assist.

Thank You,
