To prevent Artifactory from logging this, you can enable the below system property under
$JFROG_HOME/var/etc/artifactory/artifactory.system.properties for 7.x, or $ARTIFACTORY_HOME/etc/artifactory.system.properties for 6.x. 

This property will ensure Artifactory only tries to list tags from the remote repository cache, and not from the upstream.
artifactory.docker.cache.remote.repo.tags.and.catalog=<upstream url>

For example, for the error above:
artifactory.docker.cache.remote.repo.tags.and.catalog=https://registry-1.docker.io/,https://gcr.io
