URL sharing preview text with annoying OVH message?

Hey... Question..

I've changed the DNS settings for my OVH website, all is up and running..

but when you share the URL in some instances the annoying message appears from OVH with something that has nothing to do with my website..

why? is it cache issue? if so how to clear it?

http://my url example

this is the annoying message that appears?

"Félicitations ! Votre domaine a bien été créé chez OVH !
OVH accompagne votre évolution grâce au meilleur des infrastructures web : hébergement, nom de domaine, serveur dédié, CDN, Cloud, Big Data, ... "

my url: is cafegatoibiza.com

how do i remove that??

many thanks
