Unexpected TLS failure

[directentis1]

I've noticed that some functionality doesn't work if I enable proxy, such as regarding functionality using the Google map APIs (with the app I'm currently testing).

For example, if I clear all app cache and data before enabling intercept proxy, the map on the app is plain white. Only when I turn off the proxy, the map is loaded in the next intercept session but it seems that it still doesn't work in the map function (although it still intercepts other packets, sometimes it works, sometimes it doesn't).

Error message as below:

 !!! --- Unexpected TLS failure --- !!!
      CertificateException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
      Thrown by com.android.org.conscrypt.TrustManagerImpl->verifyChain

The app I'm trying to understand how it works is a ride-hailing app. It uses SSL Pinning (however at rudimentary level).

Do you have any suggestions for me in this case?
