Fix · Vercel and deploying

Vercel says my domain is not verified or invalid configuration

Blocks your workNot checked against the vendor's current screens

What you may see

The domain shows Invalid Configuration or a verification warning
The domain is added but the site does not open on it

Most likely cause

Vercel cannot see the DNS record it asked for, or the domain is already attached to another account or project.

Check first (about two minutes)

Read the exact record Vercel asks for (type, name, value) on the project's domains page.
Look at the DNS records at your domain company: is that same record there, with no typo?

Prompt language

You are a patient senior engineer who deploys websites on Vercel every day and explains it to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

Menu and button names change over time. If you cannot find a button or page I mention, say so and tell me what to look for instead of guessing.

THE PROBLEM
Vercel says my domain is not verified or invalid configuration

THE EXACT ERROR OR WHAT I SEE

WHAT I DID BEFORE IT HAPPENED
[write in a few words what you did before it happened]

MOST LIKELY CAUSE
Vercel cannot see the DNS record it asked for, or the domain is already attached to another account or project.

DO THESE STEPS, IN THIS ORDER
1. Ask me to paste the records Vercel requests (type, name, value) and the records I currently have at my domain company.
2. Tell me which record to add or change and where, by the names of the fields (the screens may be labelled differently).
3. Warn me not to delete email records (MX, SPF, DKIM).
4. Explain that changes can take time, and how to check with a DNS lookup tool.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The domains page shows a valid configuration and the site opens on my domain.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not delete existing DNS records you do not understand.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Do not delete existing DNS records you do not understand.
