Hi @SHUBHAM SINGH CHOUHAN - Thanks for reaching out.
If this was working previously, please check for below configuration if any of these got changed:
- Any kind of network limitation got applied on the storage account level such connectivity allowed only via Selected IP/VNET or PE. If yes, then try flipping the access level to allow from all network and test for isolation.
- Access level of the container got changed to Private and you are trying to access this anonymously and hence the failure.
- Public Access Level on the account level is disabled as a result it is breaking even though access level on the container is Public (Blob/Container). https://learn.microsoft.com/en-us/azure/storage/blobs/anonymous-read-access-configure?tabs=portal
I would recommend you to review these which will help in isolation. Also, what is the auth mechanism you are using for storage and can you share the complete exception, if possible.
