I can't pull docker images by my own anonymous in nexus

I wanna pull docker images from docker proxy repo, however I can’t do it.

It’s successful when I try doing it built-in anonymous user but I fail to pull by my own anonymous (privilege is nx-anonymous.

  1. in the nexus settings I changed the built-in anonymous user to my own
  2. I tried to pull Docker images with a user who has the same anonymous parameters as the built-in anonymous.
  3. I tried to pull images with even superuser privileges.

If you haven’t take a look at the help documentation for Docker Authentication
