• It's confirmed that there's no issue accessing cloud proxy port 443,4505,4506 from windows client. There's also no issue when attempting to browse file from url on windows client: https://<cloud proxy ip or fqdn>:443/downloads/salt/config-utils.bat

Environment

Aria Operations 8.18.X

Cause

The execution of powershell script is forbidden because execution policy is set to "Restricted" on windows client.

Resolution

Change the execution policy on windows client to "RemoteSigned":

1. Run a powershell command line as Administrator
2. Issue command: Set-ExecutionPolicy RemoteSigned

The execution policy applied currently can be checked with command: Get-ExecutionPolicy

Once the telegraf agent installation completes, the policy can be set back to "Restricted" if required: Set-ExecutionPolicy Restricted
