Error while using "Protractor jasmine 2 screen shot reporter" - node.js

Question

I am trying to take the "Screen shot" of the web page when the "test case fails".
I installed "protractor-jasmine2-screenshot-reporter" using "npm".
I am using below data.
1.Node -- v6.11.4
2.NPM -- 3.10.10
3.Protractor -- 5.1.2
My "Protractor.conf.js" file code below.
var HtmlScreenshotReporter = require('protractor-jasmine2-screenshot-reporter');
var reporter = new HtmlScreenshotReporter({
dest: 'C:/Users/agudla/Desktop/VSCodeWorkSpace/my-app/screenshots',
filename: 'my-report.html'
});
exports.config = {
allScriptsTimeout: 11000,
specs: [
'./e2e/**/*.e2e-spec.ts'
],
multiCapabilities: [{
'browserName': 'chrome',
'seleniumAddress':'http://localhost:4444/wd/hub'
},
{'browserName': 'firefox',
'marionette': 'false',
'seleniumAddress':'http://localhost:4444/wd/hub'
}
],
baseUrl: 'http://localhost:4200/',
framework: 'jasmine',
jasmineNodeOpts: {
showColors: true,
defaultTimeoutInterval: 30000,
print: function() {}
},
beforeLaunch: function() {
return new Promise(function(resolve){
reporter.beforeLaunch(resolve);
});
},
onPrepare() {
require('ts-node').register({
project: 'e2e/tsconfig.e2e.json'
});
jasmine.getEnv().addReporter(reporter);
},
// Close the report after all tests finish
afterLaunch: function(exitCode) {
return new Promise(function(resolve){
reporter.afterLaunch(resolve.bind(this, exitCode));
});
}
};
I am getting below error message while running the test script.
ECONNREFUSED connect ECONNREFUSED 127.0.0.1:4444
Can any one help me to solve this issue.

It is working now , i run "Selenium server" and i changed the var HtmlScreenshotReporter = require('protractor-jasmine2-screenshot-reporter'); as
var Jasmine2HtmlReporter = require('C:/Users/agudla/AppData/Roaming/npm/node_modules/protractor-jasmine2-html-reporter');
Should have to provide complete "path" for the "protractor jasmine2 html reporter".
To know the "protractor jasmine2 html reporter" path in your system , type below command in command prompt.
npm link protractor-jasmine2-html-reporter
It will print the complete path .
