Repository not working - 404 error

Issue

I recently upgraded our soon-to-be new satellite server to 6.4. Upgrade was fine and everything works normally except for the RHEL 7 Supplementary repo. It is enabled, newly synced, but when I go to a VM and try to do a yum update it fails with HTTP 404 error for the Supplementary repo. I can see it enabled and synced in Satellite WebUI.
