When signing in to the Android mobile app for Microsoft Power BI, you may see the message, “Could not authenticate because your corporate SSL certificate is untrusted by this device. Please contact your company IT admin.”
What you need to do usually depends on the operating system on your Android device, but there are a couple of other issues that may cause this error.
Look for an update for an app named Chrome, and install the update.
Your device may need a updated version of System Webview. It may be installed on your device, and you may just need to click Update.
If System Webview isn't installed on your device:
On your Android device, close Power BI.
Open the Google Play Store and search for System Webview by Google Inc.
Restart the Power BI app and sign in.
Time-zone settings on your device may be wrong.
Go to Settings > System > Date and time to check them.
If you're using a custom authentication server, the SSL certificate in the corporate authentication server may not be valid. Please contact your organization's IT admin to help you.
