Can't connect to, login timeout

This is the first time I use NodeMcu-12E and I have an issue when i upload my sketch to NodeMcu-12E. When uploading is done then I open serial monitor and it say that my board was succesfully connect to my home network, but it can’t connect to blynk-cloud, it say login timeout.

Here is the code…

#define BLYNK_PRINT Serial

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

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "c23600412c774d2c86a3302eba******";

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

void setup()
  // Debug console

  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "", 80);
  //Blynk.begin(auth, ssid, pass, IPAddress(, 8080);

void loop()

and here is screenshot of serial monitor. Hopefully i find the answer here.

Is anyone success connect to blynk-cloud server? I have the same problem…

If anyone has success run that example sketch, what version of library/IDE/etc do you use? Please share with us…

Same here, I have the same login timeout problem, anyone succeed to connect?
NodeMCU 1.0 12E
Blynk library: 0.5.3
ESP8266 ver: 1.0.0

I made it … woooooooooooo
the problem was from the internet connection, I was using mobile hotspot (tethering), and after using a real wifi router, it worked like a charm

also don’t use a corporate wifi with so much firewalls and security,


“don’t use a corporate wifi with so much firewalls and security,”
that works for me man, you saved my life lol thankyou so much. first i’ve used my router and it always said “login timeout”, until i changed my ssid to mobile hotspot (since there’s less firewall & security in hotspot) and boom my device is online in blynk app.
