I tried every pins one by one to make sure that I did not connect to the wrong pin.
Currently I connect D4(GPIO 2 for NodeMCU v2) -> R 500 ohm -> LED -> Ground.
Is that correct ?

no. because gpio2 is special pin . if led pulling down that pin , your module cant boot. can you try gpio2 to 3.3v with 500ohm resistor and led on gpio4 or 5?

... or LED can be reversed on GPIO2 with cathode on it and anode to VCC thru the resistor.
Of course, the logic will be inverted : placing LOW on GPIO2 will turn on the LED and HIG will turn it off.
