Genie 2 setup with (7) 4k minis. Need help!

I keep getting no servers detected check your network connections message on all the tvs within about 20min of watching tv. Message also says this TV input does not support 4K DirecTV service, note the tvs are all 1080 not 4k.

Any help would be much appreciated!

Here's the setup, please let me know if I need to change anything, or add some amps?

Thanks,
Darren
