An error occurred when logging in to nvcr.io

Hi,
Follow the document and enter the following instructions to log in to nvcr.io:
$docker login nvcr.io

And enter my api key
$Username: $oauthtoken
$Password:

The following error occurred:
Error response from daemon: Get https://nvcr.io/v2/: proxyconnect tcp: dial tcp 127.0.0.1:1080: connect: connection refused

Any idea? Thanks.
