Docker not logging into local repository

I have just set up a local VM running Nexus. I have configured a Docker repository on port 5000. I have a separate VM running Docker. I have configured the repository in /etc/docker/daemon.json as so:

{
  "insecure-registries": ["192.168.0.5:5000", "nexus:5000"]
}

I then restarted the Docker service. and I have run the command:

docker login 192.168.0.5:5000

I am prompted for a username and password, and when I enter them it returns with::

Error response from daemon: Get https://registry-1.docker.io/v2/: unauthorized: incorrect username or password

I have checked the Docker documentation, and other online resources on how to login to a local docker repository, but I have exactly the same configuration and it just always throws this error.

If I try to push my image, it attempts to contact the local repository, but it complains there are no credentials (as well it should):

[root@docker repo]$ docker tag repo 192.168.0.5:5000/repo
[root@docker repo]$ docker image push 192.168.0.5:5000/repo
Using default tag: latest
The push refers to repository [192.168.0.5:5000/repo]

Am I missing something?

I was experiencing the same but only with MacOS "Docker Desktop" installations. On Windows it's working as expected.

Client:
 Cloud integration: 1.0.17
 Version:           20.10.8
 API version:       1.41
 Go version:        go1.16.6

 Experimental:      true

 docker-init:
  Version:          0.19.0
  GitCommit:        de40ad0

As I am trying to login to a local registry (using Artifactory) I've checked the reverse proxy's logs. The MacOS client doesn't even try to reach the local registry.

I fixed it by updating Docker Desktop from 4.1.0 to 4.1.1. Seems like an undocumented bugfix to me.
