Here is an analysis by ChatGPT: Based on the provided packet capture summaries, I can identify some key differences between the successful and unsuccessful connection attempts. Successful Connection: TCP Handshake: The three-way handshake (SYN, SYN-ACK, ACK) completes successfully. QUIC Protocol: Successful QUIC handshake and protected payload exchanges. TLS Handshake: Successful TLS handshake with Client Hello, Server Hello, and subsequent encrypted communication. Data Transfer: Application data is exchanged after the handshake, indicating a successful connection and communication. Unsuccessful Connection: TCP Handshake: The three-way handshake (SYN, SYN-ACK, ACK) completes successfully, but there might be multiple attempts to establish a TCP connection. QUIC Protocol: Multiple QUIC handshake attempts, with several protected payload packets exchanged but potentially indicating retries or failures in establishing a stable connection. TLS Handshake: The TLS handshake with Client Hello and Server Hello is initiated but seems to have issues with the follow-up encrypted communication. Potential Retransmissions: There are multiple retransmissions and repeated attempts, indicating instability or failure in maintaining the connection.

This is the english version what we have discovered is that it works using appclip default link from appstore. It doesn't work using any associated URL. Wireshark analysis showed that iPhone comunicates with When using assiciated link: gateway.icloud.com -> FAIL When using default App Clip link: play.itunes.com, iosapps.itunes.apple.com -> SUCCESS I guess we have no possibility to influence which domain should the iPhone use
