I have build some code like this but still sent got nothing.

anyone can help me?
thank you very much regards

#include <WiFi.h>
#include <HTTPClient.h>

const char* ssid = "asdasd";
const char* password = "asdasd";

const char* serverName = "http://192.168.0.120:8087/";
unsigned long lastTime = 0;

unsigned long timerDelay = 2000;

void setup() {
  Serial.begin(115200);

  WiFi.begin(ssid, password);
  Serial.println("Connecting");
  while(WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.print("Connected to WiFi network with IP Address: ");
  Serial.println(WiFi.localIP());
 
  Serial.println("Timer set to 5 seconds (timerDelay variable), it will take 5 seconds before publishing the first reading.");
}

void loop() {

  if ((millis() - lastTime) > timerDelay) {

    if(WiFi.status()== WL_CONNECTED){
      HTTPClient http;

      http.begin(serverName);

   http.addHeader("Content-Type", "text/plain");
      int httpResponseCode = http.POST("/set/try_simple_api2?value=7");
     
      Serial.print("HTTP Response code: ");
      Serial.println(httpResponseCode);
        
      // Free resources
      http.end();
    }
    else {
      Serial.println("WiFi Disconnected");
    }
    lastTime = millis();
  }
}

@homoran

thank your for your hospitality

I have build a new system with I7 and linux ubuntu 18.04.

IObroker works wonderfully
thank you once again
regards

@homoran
i have tried 8011 and 8000 also tried 9000 and 9001.
but still the same problem.

wow, i just knew that XEON compatibility issues with iobroker.

ok will try to changes the XEON (I still not know how but will figure it out).
I'll update my trial with a new CPU asap.
thank you very much for the knowledge.
regards!

@homoran

I'm using this VM for server
but it's totally new because every time i tried a new language i create a new one then combine it to fix server i want.
I have tried php,nodejs,mqtt,python so far and all works (for learning purposes).

I'm not quite know about the AMD64 because there is not option for me to choose the type in google cloud. but here is the overall system i get from the google cloud.

I have tried run iobroker (with the instances above) but still the same error said that EADDRINUSE
even i changed it back to 9001 and 9000

Right now i will try to create a new VM

thank you for your hospitality

@homoran

should be the port and bind in iobroker list instances be like this?

 system.adapter.admin.0                  : admin                 : try1                                     -  enabled, port: 8081, bind: 0.0.0.0, run as: admin

+ instance is alive

i follow some code from the forum to changes the instances

cd /opt/iobroker

iobroker set admin.0 --bind 0.0.0.0

iobroker set admin.0 --port 8081

thank you

@homoran
thank you for the reply again!!

ok will do that
I'll inform you after i start a new VM

my debian is
debian-10-buster-v20210512

@homoran
thank you for your reply

+ system.adapter.admin.0                  : admin                 : try1                                     -  enabled, port: 8089, bind: 8081, run as: admin

+ instance is alive

I have added a new admin in 8089 but still not working
I have doubt with the version of my dependencies.
Is it because the NPM, nodejs,node, and js-controller?
my NPM version is 6.14.13
nodejs is 12.22.1
node is 12.22.1

Hello
I'm very new with this application.
I have a problem with my installation. I cannot enter the admin page with mine port 8081.

i follow this intruction for the installation :
installation pages

I have configure the port in my VM for port 8081.
I use linux debian buster with VM.

I have been searching the answer from here.

• iobroker troubleshooting

• iobroker community (off course with google translate)

I have also tried this code.

sudo node node_modules/iobroker.js-controller/controller.js --logs

and the outputs are always (even i changes the port from 9000 and 9001 to others) :
