Hello Shaik, Parvez [CTR],
Thank you for posting your query in the Microsoft Q&A Community.
A 403 status code typically signifies that the request was understood by the server, but the server is refusing to authorize it. Since this issue is happening randomly and resolves on its own after a few minutes, it suggests that the authorization configuration might be inconsistent or that there are intermittent issues with the Azure service or your network.
If your application is using tokens for authorization, the tokens may be expiring or not being refreshed properly, leading to occasional failures.
If the issue is related to a storage account which I presume, try regenerating the storage account access keys and updating your application with the new keys.
Also, verify that no network or firewall rules are blocking the connection. You might need to allow access from all networks temporarily to test if this resolves the issue.
If the issue continues to occur and you are unable to resolve it with the above steps, it might be worth raising a support ticket with Azure to investigate further.
Let me know if this helps.
