Hello,

I’m using the Microsoft 365 Tenant Assessment and there is an error when retrieving data. The error is:

Failed Get-PnPTenantSite to retrieve the private channels.
A configuration issue is preventing authentication - check the error message from the server for details. You can modify the configuration in the application registration portal. See Client Applications · AzureAD/microsoft-authentication-library-for-dotnet Wiki · GitHub for details. Original exception: AADSTS700027: Client assertion failed signature validation.

The link provided does not help locating the faulting application

Thanks
