My RHEL 7 Server unable to pull down RHEL 6 packages using reposync

Was there a recent change that prevents me from pulling down rhel 6 repo packages to my rhel 7 server? This is used for offline rhel 6 servers. I was able to pull these packages using yum utils "reposync" up until Friday Oct 20th.

Example:
[root@rhel7-repo ~]# reposync -p /var/satellite/repo/rhel6-server-x86_64/ -r rhel-6-server-optional-rpms --downloadcomps --download-metadata -l
Loaded plugins: product-id, rhnplugin, subscription-manager
