What is the issue you’re encountering

traffic is routed to an unexpected old deployment when DNS proxy is enabled

What steps have you taken to resolve the issue?

The domain eccentricprotocol.com is registered and managed with Cloudflare. When Cloudflare proxy (orange cloud) is enabled, traffic is routed to an unexpected old deployment, and calls are made to a Cloudflare IPv6 address ([2606:4700:3035::6815:1f03]:443). Disabling the proxy (DNS only) allows the correct server to be reached. I have tried hostname liberation, purging the cache, and checking for residual custom hostname or SaaS configurations, but the issue persists. Please investigate and resolve any backend routing or custom hostname issues that may be causing this behavior.

What feature, service or problem is this related to?

This is normal and is to be expected.

When a domain is proxied, the origin IP is “hidden” (so to speak) behind the proxy. All requests first go to the Cloudflare proxy before Cloudflare turns around and sends the request to the origin. This is how Cloudflare can protect the domain and offer its various CDN services.

As such, querying a proxied domain will always return Cloudflare proxy IP address(es)… and not the origin IP address.

If you absolutely need to see your origin IP, then you must disable the proxy. But note that when you do this, you’re also disabling Cloudflare’s protection and all CDN services.

Good luck!

Run a trace of the request and review any workers or pages projects which might point to the old cryptonaningans site.
