How do you get the error?

When you try to send Google API a request like https://www.googleapis.com/blogger/v3/blogs/2399953?key=…

You end up with the error warning:

Client network socket disconnected before secure TLS connection was established

The code you tried results in the error message:

const {google} = require('googleapis');
const blogger = google.blogger({
  version: 'v3',
  auth: 'YOUR API KEY'
});

blogger.blogs.get({blogId: '3213900'}, (err, res) => {
  if (err) {
    console.error(err);
    throw err;
  }
  console.log(`The blog url is ${res.data.url}`);
});
//But I can get result in browser https://blogger.googleapis.com/v3/blogs/3213900?key=xxx

Variation in code you tried:

var request = require("request");

request(
  {
    url:
      "https://blogger.googleapis.com/v3/blogs/3213900?key=xxx",
    method: "GET",
    proxy: my-vpn-proxy,
  },
  function (error, response, body) {
    if (!error && response.statusCode == 200) {
      console.log(body);
    }
  }
);

After this, you typed the following code script:

var url = require('url');
var https = require('https');
var HttpsProxyAgent = require('https-proxy-agent');
 
// HTTP/HTTPS proxy to connect to
var proxy = 'my-vpn-proxy';

var endpoint = 'https://blogger.googleapis.com/v3/blogs/3213900?key=xxx';
var opts = url.parse(endpoint);
 
var agent = new HttpsProxyAgent(proxy);
opts.agent = agent;
 
https.get(opts, function (res) {
  console.log('"response" event!', res.headers);
  res.pipe(process.stdout);
});
