Edit: I just realised the supply_node in the new URL might change from location to location, hence you'd have to find what yours would be.
Ahh, and that was it. I changed to 1791ac20-df64-4235-8d06-562cc24d22e6 which is the node I'm using and I now get the data.
For those that want their node name, I installed a TLS proxy on my Android phone and pulled it from the https trace. I used the app "Packet Capture".
