I am running simple ps cmdlets to connect to azure datalake gen2 storage, some of the cmdlets are working and authenticating through corporate proxy (powershell is configured to use proxy on my machine). however some commands are failing with "Proxy Authentication is required".

Can someone share ideas or reason or fix ?

 $subscription = "subscription"
 $storageAccount = "storage"
 $filesystem = "rawdata"
 Connect-AzAccount -Subscription $subscription | Out-Null
 $context = New-AzStorageContext -StorageAccountName $storageAccount -UseConnectedAccount

Below commands are throwing an error

Get-AzDataLakeGen2Item -Context $ctx -FileSystem $fileSystem
Get-AzDataLakeGen2ChildItem -Context $context -FileSystem $fileSystem

Get-AzDataLakeGen2ChildItem : Proxy Authentication Required At line:1 char:1

  • Get-AzDataLakeGen2ChildItem -Context $ctx
  •   + CategoryInfo          : CloseError: (:) [Get-AzDataLakeGen2ChildItem], RequestFailedException
  + FullyQualifiedErrorId : RequestFailedException,Microsoft.WindowsAzure.Commands.Storage.Blob.Cmdlet.GetAzDataLakeGen2ChildItemCommand

But this command is working fine.

Get-AzDatalakeGen2FileSystem -Context $ctx

One of the workaround for connecting to the Azure Data Lake Gen2 Storage account using PowerShell through Proxy by using following Code:

 $browser = New-Object System.Net.WebClient
 $browser.Proxy.Credentials =[System.Net.CredentialCache]::DefaultNetworkCredentials

Run this Code before connecting to the Azure Account.

I have executed this code to list the files available in the directory of my container in Azure Data Lake Gen2 Storage locally (Windows PowerShell ISE)

Windows PowerShell ISE:
