on the serial monitor, i am getting a message as " [846659] Connecting to blynk.cloud:80 [847566] Invalid auth token.

Plz help me

The code is here

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

dht.begin();

// Setup a function to be called every second timer.setInterval(1000L, sendSensor); }

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

I was receiving the same error. I fixed it by using this Blynk.begin syntax instead.

Blynk.begin(auth, ssid, pass, "blynk.cloud", 80);

It seems that Blynk has not updated their default cloud link in the default argument syntax Blynk.begin(auth, ssid, pass); but seems to expect it.
