We do not know....

What should the response be ?
Can you access the url from your computer?
Can you access the url from the native browser on your device?
How are you handling the response (When web1.got text / file) ?

3

I'm sending information to an arduino, in my project I don't need an answer, I just sent this great.

4

And my two middle questions ?

5

in arduino and in the browser it works correctly, the arduino receives the sending, but the message appears on the screen.

6

can you help me how to solve my friend?

7

You are sending to a local IP address on your home network.

Is your AI2 test device using

  • WiFi, or
  • just its cellular data connection?

If it is only on cellular data, it can only see web addresses outside your network.

8

is using wifi

9

I don't see in your blocks image the Web1 .GotText event block where you would catch the response from the Arduino.

10

can you help me how to make this block?

11

What device are you using? Arduino with a Wifi module, ESP8266, ESP32,...?

12

nodemcu 8266
