Your title has no relation with the description.

Based on the description, it clearly says site not found, so there’s no site with that name. Based on the title, there’s no built-in way to do that. You’d have to try using Edge Functions for that.

it was! and it was with like a robo verification a devloper set up for me from netfliy but now i need it to do it for my self but i dont know how

As mentioned, Netlify doesn’t have a built-in feature to do that. We cannot help with any custom-code. You can find another developer who would do this for you.
