Arduino Nano + WIZ550io - Can't connect to Blynk Cloud

Need Help With My Project
1

I’m trying to connect my Arduino Nano to the Blynk Cloud to report some very basic sensor information. To connect the Nano to the Internet I went with the WizNet WIZ550io Ethernet board. I’ve wired this up to the Nano - and ran the basic WebServer example and was able to get this working on my local network. It is worth noting, I placed the “Ethernet” library from Wiznet (https://github.com/Wiznet/WIZ_Ethernet_Library) into my Libraries folder at Documents\Arduino\libraries as per instructions from the WizNet github and some other sources. I had to comment out these lines:


if (Ethernet.hardwareStatus() == EthernetNoHardware) {
    Serial.println("Ethernet shield was not found.  Sorry, can't run without hardware. :(");
    while (true) {
      delay(1); // do nothing, no point running without Ethernet hardware
    }
  }
  if (Ethernet.linkStatus() == LinkOFF) {
    Serial.println("Ethernet cable is not connected.");
  }

As I would get an error when compiling:

exit status 1
'class EthernetClass' has no member named 'hardwareStatus'

However, once I removed these lines the webserver example worked fine.

Now when I try to connect the device to the Blynk Cloud using the Quickstart function - my nano gets an IP address from my network which I can also ping, but in the Serial Monitor all I can see is:

[5211] Connecting to blynk.cloud:80
[37394] Connecting to blynk.cloud:80
[69574] Connecting to blynk.cloud:80
[101754] Connecting to blynk.cloud:80

And the device won’t connect or show any updates either on the Blynk Cloud or on my Serial Monitor.

I copied my code from the Blynk Cloud - but leaving below in case it helps. Any suggestions/advice greatly appreciated:
