Hi,
My blynk project is constantly going OFF… Somedays it work, and somedays it is Offline… Need to restart all the time 
you know why?
I’m using the same code. I didn’t change the code.
I tested with other Arduino, and other Ethernet shield and the problem keeps.
But i’m having these days a VERY LOW net speed (like 1mb or 2) will that be cause???
Code:
#include <SPI.h>
#include <Ethernet.h>
#include <BlynkSimpleEthernet.h>
#include <DHT.h>
#define W5100_CS 10
#define SDCARD_CS 4
#define DHTPIN 2
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);
BlynkTimer timer;
WidgetBridge bridge1(V1);
static bool value = true;
char auth[] = "545db7988e09468da8bae2506b99bc25";
void sendSensor()
{
float h = dht.readHumidity();
float t = dht.readTemperature();
if (isnan(h) || isnan(t)) {
Serial.println("Failed to read from DHT sensor!");
return;
}
bridge1.virtualWrite(V20, t);
bridge1.virtualWrite(V21, h);
}
BLYNK_CONNECTED()
{
bridge1.setAuthToken("473457fa470c42edb5c6c340661e2019");
}
