Hi, the app probably uses certificate pinning.

HTTPS Sniffing on Android (Certificate Pinning)

Hi, If an app uses certificate pinning you need to manually patch the app (decompile and add the certificate) or you need to root your android device. http://docs.mitmproxy.org/en/stable/certinstall.html#certificate-pinning

Hope this helps
