@activeliang if you use build Proxyman 3.1.0 (Download), can you reproduce the bug?

@NghiaTranUIT Sorry, let me correct it: version 3.1.0 also encountered problems, I encountered the same error in both macOS 10.15.7 (intel chip) and macOS 12.6 (M1 chip)
My usage scenario is:
Capture websocket (action cable) from Web Browser, for example, this address has a websocket connection based on action cable: https://pt.hongliang.fun/ft After opening proxyman, the action cable cannot connect successfully, you can try it.
