Hello, Our iOS app has been rejected four times under Guideline 2.1(a) because sign-in fails on the review iPad. The latest rejection showed NSURLErrorDomain error -1001 (the request timed out) on an iPad Air 11-inch (M3) with iPadOS 27.0, on November 5, 2026, at about 11:54 UTC. The same happened on October 16, 2026. Setup: API: https://wp.pavilion.az, HTTPS on port 443, fixed DNS name DNS and proxy on Cloudflare (IPv4 and IPv6), publicly trusted certificate The app uses URLSession, with no custom certificate checks and no proxy settings What we checked: Neither our origin server nor Cloudflare logged any request from the review device on either day. Other clients were served normally during the same minutes. The domain resolves normally from many public DNS resolvers in the United States and Europe, over IPv4 and IPv6. The app signs in in under one second on an iPad simulator in a data center in Los Angeles, and on our own devices through TestFlight. This looks similar to https://developer.apple.com/forums/thread/773444, where a Cloudflare-hosted domain resolved to a wrong address inside Apple's network. Could someone from Apple check how wp.pavilion.az resolves, and whether it is reachable, from the App Review network? We have resubmitted a build that adds a short network check to the error message (the DNS result and which connection step fails), but each review cycle takes many days. Thank you.
