I'm using mitm on ios to test some app, but since yesterday I can't log in any website, or even use google. It seems that the certificate has expired on the 28/06. I've tried to download a new one on mitm.it, but it's already expired. Do someone have any idea how i can bypass that ?
You can force mitmproxy to generate a totally new root CA certificate by simply deleting the old one.
Mitmproxy stores the root CA certificate and it's key in the directory ~/.mitmproxy
(mitmproxy config directory in your home directory on the computer running mitmproxy).
If you rename or delete that directory and restart mitmproxy, a new root-CA certificate will be generated.
Then you can install this new certificate as usual via http://mitm.it
