@joaomoreno @atbagga, i think this issue should be in the devops cli extension repo.

[atbagga]

@joaomoreno Thank you for reporting the issue. This is not a generic issue so we will need some more details from your environment. Can you help me with the below, which will help us debug this further..

1. Are you able to run other Azure Cli commands? Try az account list.
2. Are you able to run other extensions command? I see you have webapp extension installed so you can try az webapp list
3. Please share the debug logs for the command run.. if any one of the above command (1) or (2) FAILS then sharing logs from the command run with --debug will be helpful. If the above commands work fine, share the output of the artifacts download command with --debug which is failing for you.

Thanks!
