DNS configuration is correct per Vercel's

Hi Vercel team,

Two custom domains on my project dichevre-web are stuck on "Invalid Configuration":

pre.dichevre.com (Preview/develop branch)
www.dichevre.com (Production)
dichevre.com apex (redirects to www)

DNS configuration is correct per Vercel's instructions:

CNAME pre -> 56febd3bb9ae2059.vercel-dns-017.com. (Cloudflare, Proxy disabled) CNAME www -> 56febd3bb9ae2059.vercel-dns-017.com. (Cloudflare, Proxy disabled) A dichevre.com -> 76.76.21.21 (old apex IP, currently set) TXT _vercel records present for all three.

Verification via dig confirms correct resolution:

www.dichevre.com -> 56febd3bb9ae2059.vercel-dns-017.com -> 216.150.1.129, 216.150.16.129
pre.dichevre.com -> 56febd3bb9ae2059.vercel-dns-017.com -> 216.150.16.193, 216.150.1.193

Vercel UI shows "Remove the following conflicting DNS records" listing the same IPs that the CNAME resolves to internally (216.150.x.x), which are NOT records in my DNS provider --- they appear to be the resolved targets of the vercel-dns-017.com CNAME.

I've already tried:

Removing and re-adding the domains in Vercel (didn't fix)
Waiting 30+ minutes for propagation (no change)
Verifying no conflicting A records exist in Cloudflare (confirmed clean)

Could you please force a server-side refresh of the domain verification? This appears similar to the case resolved by Amy Egan in https://community.vercel.com/t/dns-change-required/23343

Why I have the warning if my DNS configured correctly and 48 hours are already passed and no duplicates are there? DNS config (go daddy) | | a | @ |...

Thanks!
