}

@Kittiphanp_Pomoung cloud.blynk.cc server was retired more than 6 months ago.

Are you sure you are using the correct libraries?

What are the 3 invisible include statements?

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
//#include <BlynkWrongInclude.h>

here is my include.

I update the library via sketch>include library > manage library > then i select version 0.4.0
see the picture please…

@Kittiphanp_Pomoung Blynk has at least 5 libraries which need to be installed manually. See the release notes.

i (re) copy these files under document/Arduino/libraries/

Adafruit_NeoPixel
Blynk
BlynkESP8266_Lib
SimpleTimer
Time

something with me !,

@Kittiphanp_Pomoung what does Serial Monitor show or does it work now?

same issue, and same number of error

@Kittiphanp_Pomoung please update your Blynk libraries. Remove old one. Download latest Blynk library and unzip it.

i reinstall the whole things and now result like this …

is it working correctly ?

Seems like yes.

thank a lot, now i can continue coding

I had this same problem: worked fine at first, but then had connection issues. Turned out that I had installed the Cayenne library, which uses Blynk and includes its own (obsolete) copy of the library. And the Arduino IDE isn’t smart enough to use the latest version. I removed Cayenne, and Blynk started working again!

im getting this error too

im using window , wemos d1 ,Library 0.4.7

#define BLYNK_DEBUG
#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = " 375b9b7117c0470fac0c118b5af9e315";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "sha.sha";
char pass[] = "1111111111";

void setup()
{
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);
  while (Blynk.connect() == false) { // try to connect to server for 10 seconds
  }  
}

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

If this error is blynk.cc you are not using 0.4.7.
Server was changed to cloud-blynk.com around 12 months ago.
Don’t post unformatted code to the forum.

ok thank for the reply.and its work after i connect to a new access point

I formatted your code… please use this method in the future:
