I am using mitmproxy to analyse the https traffic of some Android Apps. A few days ago I was able to intercept all the traffic without any problem and now mitmproxy doesn't seem to work properly.
Some of the apps recognise the fake certificate (I guess they use certificate pinning), for some I can only see one or two http
GET requests (even for the apps that few days ago I was able to properly capture everything), and for some apps the proxy doesn't catch anything at all.
What could have possibly changed in few days? I am sure that I have configured the device correctly. I am also sure that the phone didn't update.
I would really appreciate your help.
Update: Here is the event log. This is from an app I used to be able to intercept the traffic from.
