connection not private error on android chrome

Steps to reproduce the problem:

I have installed certificate using this method on android (https://github.com/mitmproxy/mitmproxy/issues/2054#issuecomment-327735569) So before week mitmproxy works fine, google had opened successfully in android chrome browser but today i tried to open google it said your connection is not private i also clear user credential, and update mitmproxy v4, reinstalled certificate but still getting error that your connection is not private.

Any other comments? What have you tried so far?

Removed Certificate, reinstalled using adb method tried --ssl-insecure not work

This is likely caused by this error NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM I am seeing this error in Desktop Chrome browser, google recently updated Chrome to now allow SHA-1 certificates. They need to be updated. I presume they update the Chrome on Android as well.

Recent mitmproxy releases generate proper certificates, so the fix here is to 1) update mitmproxy, 2) delete ~/.mitmproxy, 3) start mitmproxy, and 4) install the new certificate.
