I deleted node_modules, I did npm install and npm update but neither
of those options fixed the issue. The code is flawless, it is simply
an issue related to node_modules and different packages.

May be there is something in your server.js file in nodejs app. Are you allowing requests from all urls ? You need to enable Cross Origin Resource Sharing.
I am following the tutorial from https://angular.io/cli, but i am unable to connect to http://localhost:4200 after using the command ng serve from my command prompt.
The page returned the following error: This site can’t provide a secure connection, ERR_SSL_PROTOCOL_ERROR
The project is compiled successfully
I had tried allowing nodejs.exe and chrome.exe to in firewall
I disabled the Proxy Server From the (Settings -> Advance Settings -> Open Proxy Settings -> LAN settings)
I tried telnet cmd>telnet localhost 4200 (successful)
I tried connecting from internet explorer, it worked but there is no content in the webpage.
The following are executed within the windows command prompt following the tutorial:

I should be able to connect to http://localhost:4200 and the page should display a welcome to test-angular page.
Solution 1: Use incognito google chrome to go to http://localhost:4200
Solution 2: Make sure you are not connected to any VPN:
Go to developer tools Chrome 3 dots > More tools > Developer tools
Right click on the refresh button > select > Empty Cache and Hard Reload
Then type http://localhost:4200
Go to developer tools
Empty cache and hard reload
Enter http://localhost:4200
Check baseUrl: 'http://localhost:4200/'
in protractor.config.js file
Till yesterday, everything was working good. Using cmd, I type ng serve, go to my browser type localhost:4200 and my website fires up.
Suddenly today, the localhost is not responding. The ng serve is working properly.
Output after typing ng-serve-

** Angular Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **
I tried different browsers, tried reinstalling angular, still the problem persists.
The message that I get on my browser is - This site can't be reached.
You can try changing your host and your port, something like this:
ng serve --host 0.0.0.0 --port 5000
Maybe it will help...
With ng serve instead of opening the URL with http://localhost:4200 open with http://0.0.0.0:4200 .
Ok I found the problem.
After Windows Update, the Firewall Settings were messed up. I restored the default settings and now it's working fine.
Moral of the Story: Use Linux!
Before starting your app making every time first compile.
Steps.
Go to your file location in CMS.
And type ng serve and wait.
Then go to localhost:4200
I'd like to run a basic Angular 2 app on an Ubuntu EC2 instance.
In my case, I installed Angular CLI, and created a new site in /var/www
ng new test
then
ng serve --port 8080
It looks like my basic Angular2 app is running fine

I know port 8080 is open in my security groups, because I just ran a basic Node JS app a few minutes ago in /var/www. When I try to go to http://[Public DNS]:8080, Safari says it can't connect. There's also nothing in my apache logs.
Turns out the real issue is this:
https://github.com/angular/angular-cli/issues/6070
I've tried editing the server.js file and running with the --publicHost option, but those aren't working. I'm using non CLI Angular with the default port 3000 and that's working on EC2 (after adding the security group settings).
