Start by reproducing docker pull openapitools/openapi-generator-online:v6.5.0 and compare the registry response for other tags from the same repository. Investigate whether the reported Docker registry error is caused by image availability, repository permissions, or throttling; done means the pull succeeds or the external cause and required fix are documented.
