[BUG/Question] MANIFEST_UNKNOWN while using selfhosted registry

I'm trying to connect your tool to our private registry (artifactory) with a docker-remote to dockerhub but it seems that we encounter errors like "MANIFEST_UNKNOWN"

Expected behavior

Version of image should be displayed, but it is not
