When adding a CNAME in Cloudflare, you’ll see an option to proxy the record (orange cloud) or leave it unproxied (grey cloud). Proxied records route traffic through Cloudflare’s edge network, while unproxied records resolve directly to the target host. For our integration to function properly, the CNAME must remain unproxied so that it always resolves to the correct service endpoint.
