Learned this one the hard way; thought it might be useful for others in my situation.

Disabled IPV6 for downloading purposes, didn’t realize the GPIO pins used the IPV6 address as loopback.

Edit: I’m utilizing a Pi 4 on Linux 5.4.51 / otherwise vanilla Raspberry Pi OS (previously called Raspbian); 4 drives.

Thanks for sharing. Can you confirm that disabling the IPV6, the top board is working fine now?

Hey Jack; it’s the other way around. If you disable IPV6 the top hat stops working. You have to keep IPV6 enabled for the top hat to work.

I can confirm it works.
