# Invalid configuration error when Cloudflare Proxy enabled

The issue has already been posted several times here; however, no one mentions my reason for keeping the proxy on.

Cloudflare provides me with free unlimited CDN services. If I disable the proxy, I will be limited by Vercel's allocated resources. Therefore, I need to keep the Cloudflare proxy enabled. Now, regarding the question of moving entirely to Cloudflare, it is not related to this discussion. I need to keep the Cloudflare proxy on, regardless of Vercel’s recommendations. My specific use case is fully supported with the Cloudflare proxy enabled. Does the “Invalid Configuration” error impact availability, or is it just a warning and everything continues to work like before?

Welcome, @revancedapp to the community!

The error is just a warning. It's purely a diagnostic warning because Vercel expects direct DNS pointing, not proxied traffic.

When Cloudflare proxy is enabled:
- Vercel can't verify domain ownership through the proxy
- Vercel sees Cloudflare's IPs instead of direct DNS pointing
- SSL is handled by Cloudflare, not Vercel

Let us know if you have any other questions!
