LoRa sx1276 only working with Uno and not Nano

I am working on making a LoRa transmitter and reciever. I currently own 1 arduino Uno and 4 Nanos. I am using the circuit from how2electronics and have created identical circuits on each board. I thought that both of these arduinos would be the same. I've switched the LoRa boards on the circuits and they both work with the Uno. I have also used a multimeter to check the connections. Are there any differenced with the nano and the uno that could cause this?
