Hi @michael-day_7391 ,
I can't really comment on what you're seeing in the Artifactory logs (i.e. [1] and [2]), but when an Access Token is specified, that token is sent on requests via a Bearer authorization header (unless Use Legacy API Header is selected). Otherwise, the Username/Password are sent via a Basic header. This happens on each and every request, regardless of whether it's a file download, api call, etc.
Probably just easier to disable authentication during the import if this keeps coming up.
OCI Registries (i.e. what you're using for your Helm charts, as opposed to a regular Helm registry) are not supported, so you'd need to export those files and use disk-based import or something like that.
Cheers,
Alana
