I am trying to sniff traffic from some of my apps on the iphone. I have charles installed. and i have installed the certificate on the iphone as instructed in charles (and i enabled the certificate on the iphone) + changes proxy to direct trafik from iphone to my computer through charles.

Everything works, i am getting trafik from the phone inside charles.

My problem is, all https called are failing for me. if i enable SSL proxy on a certain domain (let's take *.facebook.com for example) all requests give me a Failure SSL: Unrecognized SSL message, plaintext connection?.

It does not matter which app or which connection i try, i get the same error..

can anyone help me

some of the other requests has the error "Failure Client SSL handshake failed: CA certificate could not be matched with a known, trusted CA (unknown_ca)" The certificate is enabled on the phone - Amir 'Chamse' Chamma
Did you find how to solve it? - BadVolt

Starting from iOS 10.3 SSL trust for the certificate has to be turned on manually for the manually installed certificate profiles in iOS so go to Settings > General > About > Certificate Trust Settings. Under Enable full trust for root certificates turn on trust for the certificate.]]

Here is the link to apple documentation
