Issues using USB link - DSR is off - project is offline

Thanks for the help. I’m just using a plain vanilla sample script. I tried what you said and commented the parts of the script that has anything to do with the serial port, but I am having the same issue.

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <SPI.h>
#include <Ethernet.h>
#include <BlynkSimpleEthernet.h>
#include <SimpleTimer.h>

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

WidgetLED led1(V1);

SimpleTimer timer;

void setup()
{
  //Serial.begin(9600); // See the connection status in Serial Monitor
  Blynk.begin(auth);

  timer.setInterval(1000L, blinkLedWidget);
}

// V1 LED Widget is blinking
void blinkLedWidget()
{
  if (led1.getValue()) {
    led1.off();
    //Serial.println("LED on V1: off");
  } else {
    led1.on();
    //Serial.println("LED on V1: on");
  }
}

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