The serial communication is GND-GND and RX-TX and TX-RX. Sometimes the labels are wrong, but the Arduino and the Nextion display use the right "RX" and "TX" labels as far as I know.
When I look at the first video that comes up, then they say RX-TX and TX-RX of course. There is no other way.

When you ask a question or mention something, can you give links to them ?
For example links to SimHub, so we can read what it is. Links to that YouTube video (I would like to see how wrong they are). And a link to your Nano, because it could be clone that requires an extra driver. Also tell us which operating system you use.
