I want to analyze the traffic from apps installed via Microsoft Store on Windows 11. To do so I am trying to capture and decrypt the traffic but I can't figure out how to exactly do it. I have to mention that I am kind of new to network traffic analysis.
I tried mitmproxy, Fiddler Everywhere and they didn't work. Might be because they use certificate pinning and they do not trust the mitmproxy or fiddler certificates? I also tried Fiddler Classic and I was able to capture traffic from Spotify but it is still encoded, even when I press "Click to decode". For Fiddler Classic I have to mention that I used the options "Decrypt HTTPS traffic" and "Ignore server certificate errors"
