Link Landing page to domain?

I get this message trying to connect my landing page with my domain. How can I Solve this?

Problem: This domain is linked to a different site belonging to your appId.

Hi @Sandra_Otalora,
I believe you would need to create a new page or sub-page on your site that you are linking to. You would then put that new url into the “Redirect” input in campaign builder. Here is an article that should walk you through the setup, step 5 specifically.
