$vmssResourceGroup = "RG"
publicConfig = @{"UserName" = "username"}
$privateConfig = @{"Password" = "Password"}
$extName = "VMAccessAgent"
$publisher = "Microsoft.Compute"
$vmss = Get-AzureRmVmss -ResourceGroupName $vmssResourceGroup -VMScaleSetName $vmssName
$vmss = Add-AzureRmVmssExtension -VirtualMachineScaleSet $vmss -Name $extName -Publisher $publisher -Setting $publicConfig -ProtectedSetting $privateConfig -Type $extName -TypeHandlerVersion "2.0" -AutoUpgradeMinorVersion $true
Update-AzureRmVmss -ResourceGroupName $vmssResourceGroup -Name $vmssName -VirtualMachineScaleSet $vmss

It seems the profiler agent cannot connect to the storage account to download the settings file.

Can you check if the storage account still exists or the storage connection has changed?

If anything has changed, you can update the storage account in https://www.azureserviceprofiler.com/ and re-run the deployment script with the updated storage account.

If you decide to stop the profiling, you can also remove the Microsoft.VisualStudio.ServiceProfiler/ ServiceProfilerAgent extension.

Hope this helps! :)
