Not able to add helm enable OCI Private repo through Argocd GUI as well as through command line

Not able to add helm enable OCI Private repo through Argocd GUI as well as through command line using below cmd. I have checled the correct certificate is in place.

argocd repo add registry-rat.xyz.com --type helm --name reponame --enable-oci --username 'XYZ' --password 'XYZ ==> Failed

I am able to add Private repo through argocd command by passing Flag --insecure-skip-server-verification but App deployment failed using this repo with below error

argocd repo add registry-rat.xyz.com --type helm --name reponame --enable-oci --username 'XYZ' --password 'XYZ' --insecure-skip-server-verification

ERROR

Unable to create application: application spec for reponame is invalid: InvalidSpecError: repository not accessible: repositories not accessible: &Repository{Repo: "registry-rat.xyz.com", Type: "helm", Name: "oci", Project: ""}: repo client error while testing repository: rpc error: code = Unknown desc = error testing repository connectivity: helm registry login registry-rat.xyz.com --username ****** --password ****** --insecure failed exit status 1: WARNING: Using --password ****** the CLI is insecure. Use --password-stdin. Error: Get "

unauthorized: authentication required

Start by reproducing the shown `argocd repo add` commands and the application validation error, checking the distinction between certificate verification and registry authentication. Trace the repository connectivity and Helm OCI login entry points. Done means a private OCI Helm repository can be added without the insecure verification flag and an application using it validates successfully.
