Arduino is not connected to the Network for Blynk

I’m having a heck of a time here. Here’s what I am having problems with. I have an Arduino Uno with Ethernet Shield hooked up and I can see it on my router. But the Blynk app says that its not hooked up to the network. Here’s a copy of my sketch.

#include <ESP8266_Lib.h>
#include <BlynkSimpleEthernet.h>
#include <SPI.h>
#include <Dhcp.h>
#include <Dns.h>
#include <Ethernet.h>
#include <EthernetClient.h>
#include <EthernetServer.h>
#include <EthernetUdp.h>

#include <ESP8266_Lib.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = “25dd6baa21d74f329246a2102e979d4a”;

IPAddress server_ip (50, 93, 150, 130);

// Mac address should be different for each device in your LAN
byte arduino_mac[] = { 0xDE, 0xED, 0xBA, 0xFE, 0xFE, 0xED };
IPAddress arduino_ip ( 192, 168, 1, 101);
IPAddress dns_ip ( 4, 2, 2, 2 );
IPAddress gateway_ip ( 192, 168, 1, 1 );
IPAddress subnet_mask(255, 255, 255, 0);

void setup()
Blynk.begin(auth, server_ip, 8443, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);
// Or like this:
//Blynk.begin(auth, “”, 8443, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);

void loop()

Any help would be greatly appreciated. I have an Asus RTAC47U router.

these are the libraries, saw that they didn’t copy over,


Where from did you get 8443? It is wrong port. Should be 8442

that is what was on the example in Blynk. I didn’t change it. I will now and try it. Thank you

Nope. I changed it to 8443 and triggered port forwarding to that number on router, but still no communication. I see the ip address on my router, but can’t toggle it from Blynk, nor open ip on webpage locally.

We don’t have this port in our examples. Could you please point me to it?

Please try 8442 and same for port forwarding.

Is that your own server?

the 50,93,150,130 is the ip of the internet provider. it’s static.

This is should be IP/host of Blynk Server.

i don’t know what that number is. I just put the Authorization code in there. Where do I get the blink server ip?

@jrjr214 in Blynk.begin change server_ip to “” or ping to get the IP.

I just wanted to let everyone know that I did order another arduino ethernet shield. and after still having trouble for a couple days, tried it with the Ethernet2 library, and everything works great now. I still am trying to tweak it cause I want a static ip address and don’t have access to the router, but it issues a dynamic ip address and works, That’s what matters.
Thank you for all the help.
