Good to know the onboard Node-RED instance works! I’ll remember that.
Ok, so now I know your problem. Your conduit does not have an internet connection, as it’s connected directly to your computer. A computer does not act as a router, meaning you can’t download the file from the internet.
What you should do is change the “Mode” from static to DHCP, and connect it to your router. You’ll then need to log into the router and find all the IP addresses that are connected to it - keep trying the different IPs until you find the device.
Once you change the mode to DHCP, you will not be able to connect to the Conduit using 192.168.1.80 any more. Make sure that you can log into your router and find IP addresses before you change the setting on the gateway!
If you get this wrong, the easiest method is to factory reset the conduit, and the IP address will go back to default.
Don’t forget to put your computer’s settings back to “automatic” as well!
