Can't download CA certificate - Android 11

Hey,

I'm getting this error message whenever I navigate to http://ipv4.fiddler:8888

(my port is 8888 and not 8866)

see attached screenshot. What should I do?

Also, I can't seem to find how to execute these steps, can't find the QuickExec within the Fiddler platform, I'm using MacOS:

Run about:config in Fiddler QuickExec.Create new variable fiddler.certmaker.ValidDays with value 820

Please adivse

Thank you

QuickExec is functionality available only in Fiddler Classic (which is the classic tool for Windows only). With Fiddler Everywhere (for macOS, Linux, and Windows), the default port is 8866. Use this documentation article for detailed steps on how to configure your Android device alongside Fiddler Everywhere: https://docs.telerik.com/fiddler-everywhere/traffic/configure-android
