I’ve installed python 3.6.5 on my Win7, then use command: pip install mitmproxy to install the latest one and the version is 4.0.4, all is success. Then install the cert for IE.
When I start to visit web site: https://www.winit.com.cn, it reports:
502 Bad Gateway
Certificate verification error for xxxx: unable to get local issuer certificate(errno:20, depth:0)
However, if I visit other https websites all OK! Any help will be great! Thanks!
