I would like to configure my VMs using ARM template and DSC. I prepared simple DCS script in powershell, base on that using powershell command created .zip file. mentioned .zip file uploaded to storage account container. Now I want to use this .zip file to made configuration changes on my test VMs, below my ARM template. I am receiving error message New-AzResourceGroupDeployment : 10:12:09 AM - VM has reported a failure when processing extension 'dscExtension'. Error message: "The DSC Extension failed to execute: Error downloading
https://storageAccountName.blob.core.windows.net/containerName/test.zip after 2 attempts: <?xml version="1.0" encoding="utf-8"?><Error><Code>ResourceNotFound</Code><Message>The specified resource

According to the error, you can not download the zip file from the Azure blob storage account you use. Please create a sas token for the blob or set the blob access level to Public.
For example
"resources": [
{
"type": "Microsoft.Compute/virtualMachines/extensions",
"name": "[concat(parameters('vmName'),'/Microsoft.Powershell.DSC')]",
"apiVersion": "2015-06-15",
"location": "[parameters('location')]",

"publisher": "Microsoft.Powershell",
"type": "DSC",
"typeHandlerVersion": "2.19",
"autoUpgradeMinorVersion": true,
"protectedSettings": {
"Items": {
"registrationKeyPrivate": "[parameters('registrationKey')]"
}
},
"settings": {
"ModulesUrl": "<the url of you azure blob>",
"SasToken": "<the sas token for the blob>",
"ConfigurationFunction": "[parameters('configurationFunction')]",
...
