The domain was correctly linked to my Vercel project before the update, but now the Vercel dashboard shows an **“Invalid Configuration”** warning. **Steps to Reproduce:** 1. Configure a custom domain with Vercel (previously working setup). 2. Allow `DNS` propagation and confirm domain resolves correctly. 3. After Vercel’s `DNS` record update, check domain status in the dashboard. 4. Vercel reports `Invalid Configuration` and fails to issue an `SSL` certificate. **Expected Behavior:** The domain should remain correctly linked, pass configuration checks, and receive a valid `SSL` certificate. **Actual Behavior:** * Vercel dashboard shows `Invalid Configuration`. * `SSL` certificate is not issued. * Running all Vercel-provided `DNS` test tools confirms the domain is correctly configured. * Domain does not link to the app despite correct `DNS` setup. **Additional Context:** * Screenshot attached showing the `Invalid Configuration` message. * `DNS` records match Vercel’s documentation and pass external verification tools. * This issue started only after Vercel updated their `DNS` records.  system (@system) · 2026-04-08 The domain troubleshooting guide can help with most custom domain configuration issues.

Anshuman Bhardwaj (@anshumanb) · 2026-04-08 Hi @zelalemgta, welcome to the Vercel Community! I'm sorry that you're facing this issue. I can see the DNS propagation has finished for this domain. It seems like a transient issue the domain got stuck in. Could you remove and add back the domain? This should solve the issue.
