Hi, I have a problem with associated domains developing Passkeys app. Adding alternate mode(developer mode) to Associated Domains Entitlement, it works fine. But in non developer mode, CDN doesn't seem to read the AASA file. AASA file's path is: https://(host).(rootdomain)/.well-known/apple-app-site-associtation I checked the TLS certificate conditions and all conditions are met. https://support.apple.com/en-us/HT213464 https://support.apple.com/en-us/HT210176 https://support.apple.com/en-us/102028 Is there another reason why it only works in developer mode? Thanks for your reply.

Hi. I'm trying to develop a passkey app connected with a Webauthn server. There is a problem in the process of creating the Attestation Object. Since I am assigned 8445 port, I need to upload the /.well-known/ directory to that port. In the WebAuthn specification, the RPID should not include the port number. (https://www.w3.org/TR/webauthn-2/#relying-party-identifier) When initializing an ASAuthorizationPlatformPublicKeyCredentialProvider object, if I add the port number to RPID, the passkey UI will work and ASAuthorization object will be checked. But, I don't get authentication from webauthn server because the Attestation Obj is generated with RPID which contains port. Is there any way to specify the port number to check the "well-known" directory? Or is it only possible on port 443? I checked the post, but there is no more feedback, so I'm asking a question.
