Connecting to blynk-cloud.com:80 ---> login timeout

[benghara]

Hello everyone, so i made a project using wemos and dht11 sensor, i’ve already login and uploading data to blynk 4 days ago, but after i turned off my device and turn it on again my project can’t connect to blynk and always timeout while connecting. I already searching about my problem in this forum but can’t find the answer. If you can helped me, thanks!

This is my code:

#define BLYNK_PRINT Serial

#include <BlynkSimpleEsp8266.h>
#include "DHT.h"
#include <SimpleTimer.h> 
#define DHTTYPE DHT11
#define dht_dpin D4
DHT dht(dht_dpin, DHTTYPE); 
SimpleTimer timer;
char auth[] = "*******";
char ssid[] = "*********";
char pass[] = "**********";
float t;
float h;

void setup()
{
    Serial.begin(115200);
    Blynk.begin(auth, ssid, pass);
    dht.begin();
    timer.setInterval(2000, sendUptime);
}

void loop()
{
  Blynk.run();
  timer.run();
}

void sendUptime()
{
  float h = dht.readHumidity();
  float t = dht.readTemperature(); 
  Serial.println("Humidity and temperature\n\n");
  Serial.print("Current humidity = ");
  Serial.print(h);
  Serial.print("%  ");
  Serial.print("temperature = ");
  Serial.print(t); 
  Blynk.virtualWrite(V0, t);
  Blynk.virtualWrite(V1, h); 
}

*: i only blurred my token, ssid, and pass. Not really writing like that in my project

@benghara

timer.setInterval(2000, sendUptime);

Trying to read a DHT11 every 2 seconds is a bit ambitious, as they are very slow (and inaccurate|), but that shouldn’t be causing this problem.

Try rebooting your router, and if that doesn’t work try adding BLYNK_DEBUG…

hey thanks pete, add BLYNK_DEBUG at void loop? I’m sorry if my question too dumb, this is my first time using blynk

[PeteKnight]

You have to click on the link I provided and read what it says.
For the avoidance of any doubt, where it says “the first line in your code” that means the very first line at the top of your sketch.

This is what happens after i add blynk_debug and i already changed reading time of dht11 to every 5 seconds

#define BLYNK_PRINT Serial
#define BLYNK_PRINT Serial // Defines the object that is used for printing
#define BLYNK_DEBUG        // Optional, this enables more detailed prints

#include <BlynkSimpleEsp8266.h>
#include "DHT.h"
#include <SimpleTimer.h> 
#define DHTTYPE DHT11
#define dht_dpin D4
DHT dht(dht_dpin, DHTTYPE); 
SimpleTimer timer;
char auth[] = "**";
char ssid[] = "**";
char pass[] = "**";
float t;
float h;

void setup()
{
    Serial.begin(115200);
    Blynk.begin(auth, ssid, pass);
    dht.begin();
    timer.setInterval(5000, sendUptime);
}

void loop()
{
  Blynk.run();
  timer.run();
}

void sendUptime()
{
  float h = dht.readHumidity();
  float t = dht.readTemperature(); 
  Serial.println("Humidity and temperature\n\n");
  Serial.print("Current humidity = ");
  Serial.print(h);
  Serial.print("%  ");
  Serial.print("temperature = ");
  Serial.print(t); 
  Blynk.virtualWrite(V0, t);
  Blynk.virtualWrite(V1, h); 
}

someone has a similiar problem and it has solved

Connecting to blynk-cloud.com:80 --> Login timeout

Hi all, I’ve search every post I could find and can’t find the answer to this issue… I’m using an ESP2866 ESP01s, simply connected and uploaded the ESP8266_Standalone sketch with the WIFI and Auth values entered. This works fine on my D1 Mini without a glitch, but I get this on the ESP01. While it’s connected for a second or less at a time, I’m able to send commands to it, but it never remains connected longer than a second or 2: [57378] Connecting to WifiNetwork [58383] Connected to WiFi [58…

that is the link.

Hi!

Get stuck connecting to blynk.cloud, getting error: Connecting to blynk.cloud:80, Login timeout.
Even code from Blynk exemple board won’t run.
ssid and pass is correct, used in the past.
Non of following options is working;
Blynk.begin(auth, ssid, pass);
Blynk.begin(auth, ssid, pass, “blynk.cloud”, 80);
Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
NodeMCU ESP8266 ESP-12E CH340G v3 WiFi USB Development Board.
Code included folowing:

#define BLYNK_TEMPLATE_ID “”
#define BLYNK_DEVICE_NAME “”
#define BLYNK_AUTH_TOKEN “”

#define BLYNK_PRINT Serial

#include <WiFiClient.h>
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth = BLYNK_AUTH_TOKEN;

Thanks, Tomas

@Orbita this topic is about a problem connecting to blynk-cloud.com But your problem is connecting to blynk.cloud a different url, and a different problem which requires a different solution.

I’d suggest that you start a new “Need hep with my project” topic and provide ALL of the information that is requested when you do this.

Pete.
