Errors displaying a hosted website in IIS with localhost\website

Hi

On a server 2012R2 with IIS 8.5 running, I have a website that works fine on the internet eg https://http://www.website

When I try to display the website on the machine where it is hosted, I cannot get it to display eg 

http://http://www.websitehttp://www.website

The entered http://http://www.website changes to https://http://www.website

I get an Error 404. 

Any ideas how to resolve this as I need to see if this upgraded server has not broken the IIS before we go live.
