DNS - GoDaddy external domain www.domain - Site not installed

Hello,

I have set up DNS for streetbangkok.fr and www.streetbangkok.fr (and also subdomain shop) on GoDaddy.
I have then set up SSL for the first one on OVH.

But for www, the edit button of the domain is a little bit transparent, and is not clickable, and I can't set up the SSL for it. So i guess that's why when I access the site www, it displays a page OVH "site not installed".

!16|690x199

(I have the exact same setup for the .com and they are working fine).

Can anyone help me please ?

Regards,
