Hm. It’s odd.

If you don’t mind, please open System Keychain-> search for “Proxyman CA” and verify that it’s trusted?

Meanwhile, can you try with Safari app?

@NghiaTranUIT Thanks for the help. As you can see on the screenshot, it's trusted, however for safari the error message is just Couldn't connect to the server

@JosephTico I tried to download the Setapp version on M1 Macbook (macOS 12.2.1) and it work fine.

If you restart Proxyman and still encounter the SSL Error problem, it means there is something in your machine that conflicts with Proxyman.

To investigate, do you use any VPN app? or Kernel Extension? 🤔
