Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/1254

Originally assigned to: @NghiaTranUIT on GitHub.

Proxyman version? (Ex. Proxyman 1.4.3) 3.5.2

macOS Version? (Ex. mac 10.14) macOS Monterey 12.4

Steps to reproduce

XCode 13.4.1, iOS Simulator with OS 15.5
Certificate is installed on simulator as usual and is also marked as trusted within the simulator.
When running my application I only see the following message as response:

"It could be SSL Certificate Pinning, or try installing CA Certificate on iOS Simulators again (code=999)"

Expected behavior

See any SSL traffic as before.
With any iOS 15.4 simulator it is still working as expected.

Screenshots (optional)

Not sure what causes your problem.

I tested with iOS 15.5 on Xcode 13.4.1, on the Alamofire Example app. It works fine.

If you don't mind, please download this source, open Example/iOS Example.xcodeproj, and try to install the certificate on your iOS Simulator.

Make sure you reset your Simulator: Device -> Erase all Content & Data 👍

Hello Nghia,

thanks for your fast reply. I tested the Alamofire project and then again also my project, and now everything is working. Not sure if the erasing did the trick. although it would be weird if that fixed it for all simulators.
Anyway, I am happy that it now works as expected.

Thanks again and kind regards,
Brian

Glad to know it fixes. I suppose that the certificate on your iOS device might be expired. Erase the device will do the trick 👍
