Your picture indicates that your PC's IP address is <code>192.168.1.107</code>. You stated that you're trying to access your angular app on the following IP:port combination:

<pre><code>192.108.1.107:4200

Assuming this isn't a typo, using the following IP:port combination <code>192.168.1.107:4200</code> should allow you to access your angular app.

If both your desktop and phone are connected to the same WiFi (or any other local network), then use your desktop IP address assigned by the router (not localhost and not 127.0.0.1).

To find out the IP address of your desktop:

<ul>
<li>type into the command line ipconfig (Windows) or ifconfig (Unix)</li>
<li>there's going to be a bunch of IP's</li>
<li>try all of them (except the forementioned localhost and 127.0.0.1)</li>
</ul>

If your phone and your computer connected to the same network (Wifi, LAN), you can use your computer local IP address (not the public IP address) to connect from your mobile to your computer.

Note: you should allow this in your computer firewall by adding inbound role to allow accessing your computer through your mobile.

In order to make your server available in local network, you need to use the following command:

<pre><code>ng serve --host 192.168.1.107
</code></pre>

And then the app will be available on <code>192.168.1.107:4200</code> on every device in your network.

If you don't know what is your LAN address you can execute <code>ifconfig | grep broadcast</code> on unix-based OS - the first IP is your computer, or <code>ipconfig</code> on Windows machine.

I'm not sure whether this command changed in Angular 8, but none of these worked for me.

All I had to do was manually specify the port, et voilà!

<pre><code>ng s --host 0.0.0.0 --port 4200
</code></pre>

(Note that you can also use your actual IP address in place of <code>0.0.0.0</code>; both worked for me.)

<ul>
<li>Tutorial -> <a href="https://developers.google.com/web/tools/chrome-devtools/remote-debugging/local-server" rel="noreferrer">Chrome Access Local Servers</a></li>
<li>You need only to forward one port, you do it by clicking <code>Add rule</code> button which is located in <code>Remote devices</code> tab in the <code>settings</code> (see <a href="https://developers.google.com/web/tools/chrome-devtools/remote-debugging/local-server" rel="noreferrer">Tutorial</a>), then into <code>Device port</code> you write <code>4200</code> and into <code>Local address</code> you enter <code>localhost:4200</code></li>
<li>In my scenario I also needed to forward other port, because I was running my backend server on localhost too, my backend is running on <code>localhost:5010</code>, so I simply add new rule like i said above <code>Device Port: 5010</code> and <code>Local address: localhost:5010</code></li>
</ul></li>
<li>You can now visit <code>localhost:4200</code> on your phone and it should show your app

<ul>
<li>The best part is that you can open the DevTools for the tab you have opened in your phone from the desktop DevTools and easily debug your page on phone from the Desktop (inspect the elements, see console, etc...) Your page will also be reloaded after change is made in the code...</li>
</ul></li>

You could also use <a href="https://ngrok.com" rel="nofollow noreferrer">ngrok</a> to create a tunnel to have public URL. Install this program, open it with the command line by using next command:
<pre><code>ngrok http 3000
</code></pre>

Normally this would work like charm.
<pre><code>ng serve --host 0.0.0.0 --port &lt;some-port&gt;
</code></pre>
If it doesn't it could be the Antivirus, in my case I turned off Avast and it worked!

My phone and pc are in same wifi. When I run <code>ng serve</code>, I open localhost:4200 in Chrome with my PC, which works.

But I open 192.168.1.107:4200 with my mobile phone, and it doesn’t work. 

When I use <code>create-react-app</code>. It works. 

Green is angular. White is react

我的手机和电脑都在同一个wifi上。当我运行ng serve时，我会用我的电脑在Chrome中打开localhost:4200，它可以正常工作。但是我用我的手机打开192.168.1.107:4200，它不能工作。当我使用create-react-app时。它起作用了。绿色是棱角。白色是react​​
