arduino not detected by Nextion editor but detected by Simhub arduino configuration...

Hello everyone. I am a little familiar with arduino but not really with nextion editor neither Simhub. 

I'll start by the beginning. 

I've follow the numerous tutorial online and made a TFT file output from one of the template in 4.3 folder

I've connected a Arduino Nano to a 4.3 Nextion display. The wires are correctly connected. 5V on 5V, Ground on Ground, RX on TX1 and TX to RX0.

The board is showing in my device manager as USB serial CH340 (com7)

( I also tried all the USB port on my PC 3.0 and 2.0 )

When I double click on the mextion uplaoder of my template

I choosed the right serial port, didn't changed anything else and clicked UPLOAD.

So what it chowing is:

-trying all baudrate

-nextion not found

-Resetting arduino micro if required

-Upload finished Successfully

but nothing as uploaded so I uploaded it on the display via micro sd card.

So now when I connect the Arduino Nano the display is showing the idle page

After that I turn on Simhub and I scrolled down to Nextion Display.

I drop down Nextion #1 choose the same template and the right serial port. I've enable the green button beside the FPS count then I clicked apply.

The Latency is a 20ms, control debouncing at 0 and led at 0.

I went into game configuration took note of UDP port and I've tried it with and without Foward UDP checked.

Went into the game settled all the telemetry info.

Then I jump into the game and nothing is showing on the display. It stays in idle page.

I've open Simhub arduino configuration and the serial port of my Nano is showing as well as the "name" of the device (CH340)

I also tried with a arduino pro micro( I bricked it)

I've search on google, on arduino forum, on YouTube and now I am here.

Does anyone know what is going on here?

I am kind of stuck and I really need help please.
