Connecting to Blynk-Cloud.com with Node fails

[noelmcloughlin]

The blynk library (nodejs on-device app) cannot connect to blynk-cloud today.

Either it's dropping ICMP and HTTP:8441 or service is down?

$ curl 139.59.206.133:8441
curl: (7) Failed to connect to 139.59.206.133 port 8441: Operation timed out

No luck no matter what - same issue on Pi2B+ and 3B+.

pi@rasppi2b:~/iot-edge-stepping-stones/blynk$ node --version

pi@rasppi2b:~/iot-edge-stepping-stones/blynk$ nodejs --version

pi@rasppi2b:~/iot-edge-stepping-stones/blynk$ cat pi/2b/index.js 
//###########################################
// Create Blynk "Virtual Pin" for a device,
//###########################################

var Blynk = require("blynk-library");
var AUTH = process.env.MY_BLYNK_TOKEN; 
//## no difference ## var AUTH = "'" + process.env.MY_BLYNK_TOKEN + "'"
//## no difference ## var AUTH = '123456789123456789123'"

var blynk = new Blynk.Blynk(AUTH);
var v1 = new blynk.VirtualPin(1);

v1.on('write', function(param) {
  console.log('V1:', param[0]);
});

This works ...

pi@rasppi2b:~/iot-edge-stepping-stones/blynk$ sudo -E node pi/2b/testtcp.js

Fixed by commit 402a3bf

I'll use TcpClient instead.
