@Alexey I might try and resurrect the Windows node too, because I think it’s just a power supply issue - But I had another 8-terabyte drive laying around so I figured it wouldn’t hurt to start another node.
I did just discover after setting up the new node (formatted to ext4 as well) that my apartment’s ISP blocks port forwarding, so I did open a new thread to try and figure out how to get around that with a Pi.
