Docker pull / error: authenticationrequired

[ricki1234]

I tried to pull the latest docker-images and got this error:
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.10.0
Error response from daemon: Get https://docker.elastic.co/v2/: authenticationrequired

We're behind a proxy, but I set the proxy-environment in docker and a pull from dockerhub is working fine:
docker pull elasticsearch:7.9.3

Any idea, why I get this error? Unfortunately, the 7.10.0 images are not available on dockerhub at the moment....

Thanks

Are you still seeing this?

Yes, still the same error-message
Thanks

Is there a proxy in your network? I just ran that command and it's downloading now with no auth.

Yes, there's a proxy, but as I already wrote - pull from dockerhub does work fine.
