Slow Website Loading and App Content Loading in iOS Device with Proxy Configured

K | Last updated: May 17, 2018 12:28PM UTC

Hi, I'm using an iMac with the Proxy Listener set up and have set it up correctly on my iOS device. I can see some of the http history appearing in the listener when websites are browsed in the browser, although it is slower to load than without the proxy. However, apps like Facebook or Reddit don't manage to load any content at all.

It's possible that the native apps are not using the CA certificate that you have installed on the device. Some native apps use their own certificate trust store, and some implement certificate pinning to only trust specific server-side certificates. In this situation, breaking the SSL tunnel is non-trivial and may entail jailbreaking the device or using some other advanced tools.
