Hello @Manu Cohen-Yashar ,
Thanks for the question and using MS Q&A platform.
From the error message it seems like purely a permission issue to your ADLS Gen 2 account.
When you say reader access, have you given Storage Blob Data Reader
role on your ADLS Gen 2 account or just Reader
access?
In case if your ADLS Gen 2 account has firewall restrictions to allow only selected networks then please follow below steps from the documentation: Microsoft Purview- ADLS Gen2 Authentication for a scan
Hope this info helps. Do let us know how it goes.
Thank you
