Azure Logic App Standard outbound Vnet integration notworking with storage account

Question

I am trying to access an existing storage account using Logic App workflow. Storage account can only be access via private link. We have private endpoint configured and DNS for storage account and access is working from other applications but I am unable to query storage account using Logic app workflow. I can access storage account only when access from all the networks are allowed otherwise I get 403.

I am using using managed Identity for authentication and it works well once external access to the storage account is allowed. Storage account private link IP is in the same vnet as Logic app outbound subnet. vnet is linked to private DNS zone & VM in same subnet can resolve and access storage account
