Docker login failing with v2/ failed with status: 404 Not Found

Sonatype Nexus Repository
1

I have deployed Nexus repo manager 3 in an EKS cluster.

An AWS network loadbalancer, listening on port 443 forwards traffic to my nexus service. My ingress controller in nginx. My ingress config is

k describe ing ingress-nxrm
Name:             ingress-nxrm
Labels:           <none>
Namespace:        nexusrepo
Address:          172.20.228.55
Ingress Class:    nginx
Default backend:  <default>
Rules:
  Host                        Path  Backends
  ----                        ----  --------
  nexus.pe-dev.securekey.com
                              /   nxrm-service:80 (10.107.1.109:8081)

My nexus service targets port 8081

k describe svc nxrm-service
Name:              nxrm-service
Namespace:         nexusrepo
Labels:            app=nxrm

In the UI, firstly I have enabled Docker Bearer Token in Realms

Secondly I created a Hosted Docker Repo and configured it as such

When I try to do a docker login, this is what I get

docker login nexus.pe-dev.securekey.com
Username: admin
Password:
INFO[0002] Error logging in to endpoint, trying next endpoint  error="login attempt to https://nexus.pe-dev.securekey.com/v2/ failed with status: 404 Not Found"
login attempt to https://nexus.pe-dev.securekey.com/v2/ failed with status: 404 Not Found

Although I can reach the endpoint

telnet nexus.pe-dev.securekey.com 443
Trying 10.107.37.7...
Connected to ingress-lb-4d43a5e4d210901c.elb.ca-central-1.amazonaws.com.
Escape character is '^]'.

Something I might have missed here ?

I noticed that if I specify the HTTP connector on port 80, I get the error in logs

2023-02-02 15:32:29,146+0000 ERROR [qtp1841338724-78] admin org.sonatype.nexus.bootstrap.jetty.ConnectorManager - Could not start connector: DockerConnectorConfiguration{repositoryName=main-docker, scheme=http, port=80}

Remember that on *nix ports lower than 1024 are restricted.
