certificate_unknown error in eventlog.

[shownb]

1 On my Android device, I can see: Settings -> Security -> Trusted Credentials show the new “Portswigger CA” as a system trusted CA.

2 If I'm not running Nope-Proxy, but only invisible proxies on port 8080, I can intercept all traffic on ports 80 and 443 HTTPS.

3 If I run like Nope-Proxy/wiki option, it will display an event log similar to this:
The client failed to negotiate a TLS connection to play.go***.com:443: Received fatal alert: certificate_unknown

I exported the burpca.p12 file to /opt/BurpSuiteCommunity and ~.NoPEProxy and ~, but it didn't resolve the issue.

Am I missing something?
