401 Unauthorized error on performing docker pull for private registry

Seeing below error on wget:, where as ‘docker pull busybox’ is working good. Can you please help ?

wget https://registry-1.docker.io/v2/library/alpine/manifests/sha256:51b67269f354137895d43f3b3d810bfacd3945438e94dc5ac55fdac340352f48

I’m not sure what you are trying to achieve. You say pulling the busybox image works, but I don’t see hot that could be compared to a HTTP request done by wget.
