Hey @jesus-qt, thanks for your report.

Unfortunately, It's not a bug from Proxyman. I suspect that these apps are protected by using SSL Pinning. It's designed to prevent Proxyman or other debugging proxy apps to intercept their HTTPS traffic.

There is no solution to bypass the SSL Pinning unless you have a certificate key.

Ah, I missed reading it. I'm downloading the Monster Legend app on my phone and try to reproduce it now 👍

I tried Monster Legend and it works totally fine after I set the HTTP Proxy to Proxyman Mac, but not Enable SSL Proxying.

Bunch of Monster Legend HTTP Request that I can see it in the plain text
The game work fine. I'm able to play the game as usual.

I could not test with Minecraft since it's required to pay upfront.

It seems that you have to see the DNS to 1.1.1.1 or 8.8.8.8 in both Mac and iOS devices:

on macOS: System Preference -> Network -> Wifi -> DNS -> Set 1.1.1.1
on iOS: Setting -> Wifi -> Your wifi hotspot -> DNS -> Manual -> Set 1.1.1.1

Then try again 👍

Second question: After you change the HTTPS Proxy from your iOS devices, are you able to visit the Internet? By opening https://google.com on the Safari app?
