I previously had several custom domains connected to projects on my old Vercel account. Those projects have now been completely deleted.
Problem
I am currently trying to use the same domains on a different Vercel account with new projects. The domains are verified successfully (blue checkmark), and the DNS records are correctly configured, but the domains keep showing a 404 NOT_FOUND error.
Current Behavior
It seems like these domains are still internally linked to the deleted projects from my old Vercel account (ghost domain mapping), even though those projects no longer exist.
I do not see any option to release or detach these domains from the old account, and there is no clear way to contact support directly from the dashboard.
Could you share the domain in question and the production deployment URL (uniquely assigned by Vercel to each deployment) here so we can debug this together?
