    Hi AusSupportin70,
    Thank you for reaching out to the Microsoft Fabric Community Forum.

    At this point, the issue appears more likely related to the TLS/SSL handshake between the Fabric VNET gateway and MongoDB. Even with allowConnectionsWithoutCertificates:true, TLS negotiation must still succeed because MongoDB is configured with RequireTLS.

     

    Could you test the connection from the VM using mongosh with TLS enabled and verify whether the MongoDB server is using a self-signed certificate or a certificate whose CN/SAN does not match the server name? It would also help to review the MongoDB logs for any TLS/SSL handshake failures or rejected connections during the Fabric connection attempt.

    I hope this information helps. Please do let us know if you have any further queries.

    Regards.
