IIS7 add binding site (liaison in french)

I add a site binding in IIS7
and restart Lucee (v4.5)

first binding is : mysite.fr
second is : www.mysite.fr

The second , www.mysite.fr is not working (page cannot be dispayed)

Boncode is installed, working for other sites.

I tried adding the lines HOST in file server.xml and restart Lucee.

(Host name="demeter04.fr" appBase=""
			Context path="" docBase="D:\SitesPlarts\C030\www" /
			Alias www.demeter04.fr /Alias

With no success

Thanks for any idea , advise, help.
