Cannot backup iPhone 6 or iPad when connected to a hotspot?

[iMore Question]

I have an iPad Air 2 and iPhone 6 both have hotspot through my carrier I try to do backups with one acting as a hotspot and then switch but neither will backup I can backup no problem on a wifi connection but not with the hotspot connection. Any ideas why? Thanks
