Connect-PnPOnline with ClientId and ClientSecret throwing error: The remote server returned an error: (401)

[prakashkumarsingh514]

Hi,
I created App Id and granted Sites.FullControl.All under Application.
But while running below command using ClientSecret:
Connect-PnPOnline -Url $siteurl -ClientId $clientID -ClientSecret $secrt
It gives error : Get-PnPSite: The remote server returned an error: (401) .

But while running using Certificate Thumbprint:
Connect-PnPOnline -Url $siteurl -ClientId $clientID -Tenant $tenant -Thumbprint $certThumbPrint
Its working fine and Get-PnPSite showing correct result.

I Installed latest PnP.PowerShell version 2.12.0
But still ClientSecret command throwing error.

Please suggest.
