It seems like your device can't see the flows repository. So check your internet connection to

Sorry, I'm new to the industry, how do I do this?

your device (where node-red is running - not where the browser is running) needs internet access to download extra nodes.

i start node-red on putty

ok, cool, but does the device/computer/server where node-red is actually running/executing have internet access?

i'm connected to the wireless network and to be able to start node red since i use a
iot2050 i use an ethernet cable to access the ip

Just because your computer can access the internet does not mean your iot2050 device will suddenly have internet access because you connected a cable to it.

Your device needs to be able to reach the internet.

That likely means you need to connect the device to a routed network and be on the correct subnet.
Also, if you are in a corporate setting, you will likely need proxy settings setup for the device.

Assuming you are in the workplace, you need to contact your IT people.
