Hi Paris, Thanks. trendyol.sa / trendyol.ae are behind Cloudflare; no IP/path block on .well-known (HTTP 200). As a temporary workaround, we served a Cloudflare cert only on .well-known, and verification succeeded. We need to understand why it fails with the main-domain certificates: https://trendyol.sa https://trendyol.ae What specifically fails in Apple’s TLS check on these certs, and can Cloudflare cause this even when the domains are publicly reachable? Thanks, Beyza
