I am trying to perform a M-I-T-M using Charles proxy with my android(Kitkat) device, i have installed charles Certificate both in my Desktop and as well as in my mobile phone. I have also set proxy manual with ip of my Desktop and using port 8888 which is the default port to use charles, i have also added my mobile ip in my Charles with enabling SSL proxy settings. Now when i am trying to open any website in my desktop then everything is working fine, but the problem happening is when i am trying to open any Https website in my mobile then i am getting ERR_CERT_AUTHORITY_INVALID. I have seen many solutions and none of them are working for me.
I have also seen this post SSL Proxy/Charles and Android trouble and i have done the same thing which is mentioend in the answer but still i am facing this problem.
Anyone Please help me why this error is happening.
