GUP issue

Our GUP at a remote site isn't receiving updates and as such isn't pushing them out to that site. Everything looks fine, it's connected to the SEPM server, the server can apply the latest policy, so I'm confused. Something odd shows in the system log. "Using Group Update Provider type: Multiple Group Update Providers" is listed every couple of minutes. There are patches in the log where is shows "Downloaded new content update from Group Update Provider failed. Remote file path: http://x:2967/content/{535CB6A4-441F-4e8a-A897-804CD859100E}/140829003/Full.zip"

Any ideas?

Thanks
