Problem with connecting proxy. 
	There are two outcomes when connecting a proxy: 
	1. The proxy is working - the code is being executed. 
	2. The proxy is working - but the code is not executed and there is no error in the console, because of this I cannot trace the problem and solve it. 
	 
	How can I track this error? I will be grateful for help
 
	Code:
 
const SteamClient = require('steam-client');
const SteamUser = require('steam-user');
let user = new SteamUser({
  singleSentryfile: false,
  promptSteamGuardCode: false,
  dateDirectory: null,
  httpProxy: 'http://IP:PORT'
});
user.logOn({ accountName: 'USERNAME', password: 'PASSWORD' });
user.on('error', e => {
console.log(e);
return;
});
user.on('emailInfo', function(address, validated) {
    if (validated == true) {
        console.log('Yes', validated);
		return;
    } else (validated == false) 
	{
        console.log('No', validated);
		return;
    }
});
