I am using nexus as a Docker container, with tag sonatype/nexus3:3.14.0. Also, I connect nexus with LDAP for user better user management it is helpful for group and role management.
For my case, I create a blog-store and create two docker registry repository, one hosted and one group. I try to log in, on hosted and it works fine. But when I tried to connect into the grouped repository I get 401 Unauthorized. I also tried to connect with admin credentials but I get the same error too,
Error response from daemon: login attempt to https:///v2/ failed with status: 401 Unauthorized.
Suggestions are welcome PParthenis
Enable the Docker Bearer Token Realm in Nexus Security->Realms Tab.
