I am having the same issue. My serial console just constantly shows Connecting to blynk-cloud.com:8442
I used the following sketch:
#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[] = "xxx";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "xxx";
char pass[] = "xxx";
void setup()
{
Serial.begin(115200);
Blynk.begin(auth, ssid, pass);
}
void loop()
{
Blynk.run();
}
