Nextion HMI trigger attachpop but arduino not set nextion value

I have a problem with netxtion communication. Everything worked just fine but today there was a communication problem.

arduino to nextion data is not going but when i touch and triggered attachPop, is working and print serial. I Change the serial port but get same result.

When i test on nextion editor simulator, this work is just fine. Simulator change the label and values, and simulator send to arduino.


Nextion > Arduino data SENT

Arduino > Nextion data ERROR

Arduino > Simulator SENT

Simulator > Arduino SENT

Do I make a mistake in the arduino?

PS: Used itead nextion arduino library.
