"404 Resource Not Found" From Azure Blob Storage Document from PUT

Solution 1:

Have you checked the security settings of the Blob container? It might be that you don't have enough access rights.

Solution 2:

1 - In the Azure Storage Explorer application do these steps to change/verify access.

1. Right click the container's blob in question
2. Select Set Public Access Level
3. Set to at least Public read access for blobs only.
4. Apply.

OR 2 - or In the Azure Portal Panel select

• Storage account >
• from Blob service Section Select "Blob" >
• Select Blob or Blobs that you want to change the access permission >
• Select "Access policy" >
• from the Drop Down menu select "Blob" or "Container" anonymous access based on your needs

Solution 3:

Check your container. In the new portal, click the ellipses next to it and Edit. Then set the Access type to either Blob or Container if you want to allow listing of the container.

Microsoft seems to have bumped up the security and made new containers private by default.
