ESP8266 on Nodemcu with blynk

Hello there, I hook up the nodemcu with blynk and it works fine, I can control my relay through my phone, however it only works about few seconds, then it appears to has some exceptions then restart to reconnect the wifi over and over. Sometimes the connect never build up and I’m a little confused about this, really appreciate if anyone can help me with this.

Can’t autodetect firmware, because proper answer not received.

My code is :

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

char auth[] = “authcode”;

void setup()
{
Serial.begin(9600);
Blynk.begin(auth, “ssid”, “pass”);
}

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

Hello, please try latest blynk library from trunk.
