Mitmproxy not working

[RowanG1Bilue]

I have run the cli, deployed an app, and have opened the mitmweb. It says "connected", but I don't see any traffic, and the channel can't successfully make network requests. I get this error:

127.0.0.1:60659: Transparent mode failure: RuntimeError('Insufficient privileges to access pfctl. See https://mitmproxy.org/docs/latest/howto-transparent/#macos for details.')
127.0.0.1:60660: Transparent mode failure: RuntimeError('Insufficient privileges to access pfctl. See https://mitmproxy.org/docs/latest/howto-transparent/#macos for details.')

Hi @RowanG1Bilue , that looks like a permissions error. Have you followed the linked steps in the error message?

I think the main issue is that I was trying to connect the Roku and PC via Wi-Fi, but I see now that you need a ethernet connection with a 10/100 speed adapter.
