    From what I hear from friends, it seems that Fabric excels in obscure error messages. For error code 403, here is a generic description of what it means: https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Status/403

    A better place to ask might be the Fabric communities: https://community.fabric.microsoft.com/

    Hello @Verma, Namrata ,

    Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

    Based on verbatim 403 typically means Fabric/Dataflow Gen2 can reach the service, but the request is being denied due to permissions, tenant settings, capacity/workspace configuration, or a temporary Microsoft service issue.

    Based on Microsoft Fabric guidance the most common causes are:

    (1) Insufficient permissions on the Lakehouse

    (2) Lakehouse and Dataflow are in different workspaces/capacities

    (3) Private Link / Network Restrictions

    (4) Tenant Settings Restrictions

    (5) Corrupted/Failed Connection Metadata
