The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points.

You can also use v0 to narrow down the possibilities.

The issue here is that your DNS is currently proxied through Cloudflare, which is causing Vercel to show that invalid configuration message. Vercel's DNS validation can't complete properly when Cloudflare's proxy is active between your domain and Vercel's servers.

Here's what you'll need to do to fix this:

• Log into your Cloudflare dashboard
• Find the DNS record pointing to Vercel
• Click the orange cloud icon to disable the proxy (it should turn grey)
• Wait a few minutes for the DNS changes to propagate

Once the proxy is disabled, Vercel should be able to validate your domain configuration properly and the error should clear up.

Hi Pauline, Really appreciate your attention and reply to this issue. I have already done what you suggested before posting the issue here. The problem is that I can not edit the nameserver to update to point to vercel. I also tried clicking the edit button on vercel domain page to change or update, but it is disabled. When I disploy useing vercel –deploy locally in my computer, it says something like “we are trying to issue SSL for this domain”
