Доверительная привязка для пути сертификации не найдена в проекте Android ⇐ Android

[Anonymous]

I have an Android project and it works well at my test environment with test environment certificate. And now, I must connect this app to client's UAT environment instead of test environment. From client's web site, I downloaded public certificate and added it to Android application with replacing test environment certiface. When I tested application, I took below error.

What does this error mean? Is the error about server side config? Should I add this certificate to trusted certificates of Android OS?

EDIT: The downloaded certiface from the client's web site is CA certificate. Not a self signed certificate.
