get-access-token failed

> ### `az feedback` auto-generates most of the information requested below, as of CLI version 2.0.62

**Describe the bug**
It failed when getting access token:
`az account get-access-token --q accessToken -o tsv`
If it fails by design, is it possible to fail elegantly?

(**'Connection aborted.', OSError("(104, 'ECONNRESET')"**,))
