Bitnami developer here. We have our helm charts in Docker Hub using OCI, and we’re having several users with stability issues, getting errors like this:

Error: could not download oci://registry-1.docker.io/bitnamicharts/common: failed to authorize: failed to fetch anonymous token: unexpected status from GET request to https://auth.docker.io/token?scope=repository%3Abitnamicharts%2Fcommon%3Apull&service=registry.docker.io: 401 Unauthorized

Is there any solution to avoid these issues when using OCI?

I could reproduce the issue. I don’t know why it requires logging in to run helm install, but it worked only when I logged in to Docker Hub. Would you report the issue on the Hub Feedback?

Or as a verified publisher with many useful content, you could probably speed up the process by contacting Docker Support as well.

For future readers: it seems that the bug is not in Docker Hub, but helm itself:
