Arduino错误所有重载的'println（long unsigned int（＆）（））'都是不明确的

这是我的代码

#include<SPI.h>
#include<Ethernet.h>

byte mac[]={0xAA, 0xAB, 0xAC,0xAD, 0xAE, 0xAF};
IPAddress ip(192, 168, 1, 86);
EthernetClient client;
byte server[]={192, 168, 1, 61};

void setup()
{
  Serial.begin(9600);
  delay(1000);
  Ethernet.begin(mac, ip);
}

void loop()
{
  if(client.connect(server, 80))
  {
    client.println("GET /ardunio/ardComm.php?param=ping");
    client.println();
   client.stop();
  }
  Serial.println(millis);
}

这是错误
