If you have successfully installed the Charles root SSL certificate and can browse SSL websites using SSL Proxying in Safari, but an app fails, then SSL Pinning is probably the issue. Because the app is itself verifying the root certificate it will not accept Charles's certificate and will fail the connection. Most browsers will have a way to configure this manually, but configuring manually is annoying because you have to configure and reconfigure everytime you start and stop Charles.

Note that some apps implement SSL certificate pinning which means they specifically validate the root certificate. Browser & System Configuration In order for any browser (or any application) to use Charles it must be configured to use Charles as its proxy server. On the device, set your HTTP proxy to use Charles, and then browse to to install the certificate. If the SSL site is only being used to load resources such as images, then you'll need to visit it directly and accept the certificate before it will work. If you're only browsing a single website in Safari you can just accept the certificate in Safari and that will work for that site.
