Hi,
It happened to me after I did dist-upgrade. apparently it caused by kali upgrading libssl to version 1.0.2-n1.
I resolved this problem after downgrading libssl by:
apt-get install libssl1.0

and then I reinstall mitmproxy to version 0.18.2 (the last version with python2.7) the mitmproxy has to be the one with python2.7 as the recent release, mitmproxy has dropped support for python2.7. here is what i did

pip install mitmproxy==0.18.2 typing

and you should be set
