The error message BlobNotFound means the URL being opened points to a blob that does not exist in the target container. A blob must first be created (uploaded) into a container in an Azure Storage account, and then that blob can be accessed via its URL or a SAS URL.

To create a blob using Azure Storage Explorer:

Open Azure Storage Explorer and sign in
- On first launch, in Microsoft Azure Storage Explorer – Connect to Azure Storage, select Subscription.
- Choose the appropriate Azure environment and sign in.
- After sign-in, select the subscriptions to work with and choose Open Explorer.
Create a blob container
- In the left Explorer pane, expand the desired storage account.
- Right-click Blob Containers and select Create Blob Container.
- Enter a name for the container and press Enter. The new container appears under Blob Containers.
Upload (create) a blob in the container
- Select the container that was created.
- On the container ribbon, select Upload.
- Choose whether to upload a File or Folder.
- Select the file(s) to upload.
- Choose the blob type (Append, Page, or Block). For most files, use Block blob.
- Optionally specify an Upload to folder (optional) path inside the container.
- Select Upload. When the upload completes, the new blob appears in the list of blobs for that container.
Verify the blob exists
- With the container selected, the main pane lists all blobs in that container.
- Confirm that the blob name in this list matches the name used in the URL or SAS being opened. If the name or path differs, update the URL or regenerate the SAS.
(Optional) Generate a SAS URL for the blob
- Right-click the blob and select Get Shared Access Signature....
- Set start time, expiry time, and permissions, then select Create.
- Use the generated SAS URL to access the blob. If a BlobNotFound error still appears, confirm the container name, blob name, and any virtual folder path in the URL exactly match what is shown in Storage Explorer.

Once the blob is successfully uploaded and the correct URL/SAS is used, the BlobNotFound error will no longer occur.
