@Md Saifi Thanks for posting your query on Microsoft Q&A.
Network traffic is denied if the virtual network (VNET) and firewall rules are configured on the storage account, unless the client IP address or virtual network is allow-listed.
- Ensure that virtual network and firewall rules are properly configured on the storage account.
- To test if these rules are causing the issue, temporarily allow access from all networks to verify connectivity by changing the setting on the storage account to Allow access from all networks. To learn more, see Configure Azure Storage firewalls and virtual networks.
