Bolt as a MoCa bridge; what am I doing wrong

Hi all - I have 3 TiVo Bolts, one of which is connected to my router, and 2 that use WiFi. The 2 on WiFi have massive issues streaming videos to each other, and only slightly fewer issues getting video from the Ethernet connected Bolt. After some digging, I was like, "Duh, just set the Ethernet connected one up as a MoCa bridge". So I tried that, and it gives me a message about not being able to connect to my MoCa network (image attached)...... am I misunderstanding what the Bolt is supposed...
