Restoring a site - receiving strange error message

Hi,

I am trying to restore a site with the following command:

restore-spsite -identity https://rcdemo.companyname.com -path d:\backup\bilingualsite.bak -hostHeaderWebApplicationhttps://bi.companyname.com -databasename wss_content_rcdemo - force

However, I am receivng the following error message:

"WARNING: The port specified for the new host header site does not match any known bindings in the specified Web Application.  The new site will not be accessible if the Web Application is not extended to an IIS Web Site serving this port."

Please note that the web application https://bi.companyname.com is bound to ports 90, 91 and 443. Any ideas on how I can fix this issue?

thanks,

Sherazad
