Safari Takes 30 Seconds to Load mTLS-Enabled Sites Unless in Private Browsing

I’m experiencing an issue where Safari takes approximately 30 seconds to load web pages on mTLS-enabled sites. However, when I enable Private Browsing mode, the problem disappears. This suggests that the issue is not related to the network environment.

To provide more context, I’ve attached a Wireshark packet capture for reference. From the logs, it seems that the TLS handshake process encounters delays, but I cannot identify the exact cause.

Has anyone encountered a similar issue or can provide insights into what might be causing this behavior? Any troubleshooting suggestions or fixes would be greatly appreciated.

OS: iPadOS 18.2.1

Thank you!
