Charles proxy doesn't work on my IOS device

Question

Here's what I did so far:

1. Install Charles on my mac
2. Connect mac and iPhone to same WiFi network
3. Charles->Proxy->SSL Proxy Settings. Enable for *
4. General->About->Certificate Trust Settings and enable full trust for the Charles Proxy certificate.
5. Charles->Help->Install Charles Root Certificate on a Mobile Device
6. Configure iPhone to proxy to IP provided in step 3.

And then when I try to go to safari on my Iphone I get a "connection lost" error and It's impossible to browse.

Any solutions ? I'm on IOS 11.4

Answer 1

I used to have the same problem when SSL Proxying on iOS device then I changed to the following steps and it works:

1. Install Root Certificate on my mac
2. Configure Wifi Proxy on iOS device to Charles:
   • Server: 172.16.1.191
   • Port: 8888
3. Open Safari on iOS device:
   • Browse to chls.pro/ssl to download and install the certificate
4. Install Charles CA Certificate on your device:
   • iOS ≥ 10.3: Setting app > General > Profiles > Select Charles CA > Install
   • iOS ≥ 12.2: Setting app > Profiles Downloaded > Select Charles CA > Install
5. Trust Charles CA Certificate on your device:
   • Setting app > General > About > Certificate Trust Settings > Switch ON on Charles CA

Honestly, this is based on the iOS Setup Guide of an app named Proxyman. They have similar features like Charles but the UX is better I suppose. Anw, hope it helps :)
