Could not authenticate because your corporate SSL certificate is untrusted by this device.

We are currently in the onboarding phase with office 365 and had previously tested the PowerBI app with the .onmicrosoft credentials &  everything was working fine

Currently Our users are trying to login with the domain account to the PowerBI app from their Android devices but are getting an Error Couldn’t authenticate because your corporate SSL certificate isn’t trusted By this device. Please contact administrator

We have ADFS in our environment and Forms and windows based authentication is enabled , this issue is seen across all Andriod devices 

So far we have tested with Multiple Android devices and all of them have the same result

My own android device is  ASUS XENFONE Android Version 8.1.0 power bi and other apps are latest and up to date 

We have tested by installing the certificate on the phone device and the error changes to cannot authenticate contact your administrator

I have updated Chrome and Andriod system viewer to the latest version and tested but still doesn’t work

IOS works fine no issues , please advise on how to get this to work on Andriod

We raised a support request with mpbisup@microsoft.com and were suggested to follow the steps mentioned here

We will be making the changes over the weekend so will update this post next week to update if this worked for us

This really does not sound like a Power BI issue. There are likely much better forums for your issue. But, you may luck out and someone else has seen something similar.
