Howdy, & welcome to our community!
You’ve misconfigured our system - turned on our DNS hosting, which you don’t use. Please:
- delete that invalid configuration, here: Netlify App
- follow the instructions in this post to set up your DNS at OVH to point to our service: [Support Guide] How to use Netlify’s branch deploy feature without Netlify DNS
- let us know it is in place and we can add to the certificate for you!
