Hello Apple Support, While attempting to staple a notarization ticket for our signed installer package, the stapler command fails with Error 65. Upon investigation, we found that connections to oscdn.apple.com present an SSL certificate issued to a248.e.akamai.net, which does not include oscdn.apple.com in its Subject Alternative Name (SAN). This mismatch prevents our macOS environment from validating tickets and completing the stapling process. Steps tried: Verified notarization status (Accepted). DNS flushed, tried different DNS (8.8.8.8, 1.1.1.1). curl to oscdn.apple.com consistently fails with SSL error 60. Please advise on resolving this certificate mismatch. also when I try to run the stapler command with my pkg "xcrun stapler staple/Users/mactest/Desktop/IPMPlus_Macos_Installer.signed.pkg" getting the output like :- Processing: /Users/mactest/Desktop/IPMPlus_Macos_Installer.signed.pkg Could not validate ticket for /Users/mac-test/Desktop/IPMPlus_Macos_Installer.signed.pkg The staple and validate action failed! Error 65. please help Thank you.

I am facing an issue while trying to staple a notarization ticket to my signed macOS installer package. Details of my setup: The .pkg file is signed using my Developer ID Installer certificate. The app inside the package is signed using my Developer ID Application certificate. Notarization via xcrun notarytool completes successfully with status: Accepted. However, the stapler command fails with the following error: xcrun stapler staple -v /Users/mac-test/Desktop/IPMPlus_Arm_Installer_signed.pkg Processing: /Users/mac-test/Desktop/IPMPlus_Arm_Installer_signed.pkg Could not validate ticket for /Users/mac-test/Desktop/IPMPlus_Arm_Installer_signed.pkg The staple and validate action failed! Error 65. I verified that all other Apple notarization-related servers (api.apple-cloudkit.com, gs.apple.com, ocsp.apple.com, ocsp2.apple.com, crl.apple.com, developer.apple.com) are reachable. However, the domain cdn-apple-cloudkit.apple.com cannot be resolved from any network, including mobile or public Wi-Fi. Both dig and nslookup return “No answer” even when using external DNS servers like 8.8.8.8 or 1.1.1.1. It appears that cdn-apple-cloudkit.apple.com might be required during the stapler validation process, but the DNS for this domain is not resolving. Could you please confirm whether this CDN endpoint is required for stapling, and if there is currently an outage or configuration issue with cdn-apple-cloudkit.apple.com?
