Apache shutdown unexpectedly using XAMPP Server || XAMPP, Apache - Error: Apache shutdown unexpectedly || Apache shutdown Unexpectedly solution

As working in a corporate or novice's webserver environment, developers faces firewall issues while using Apache in XAMPP Control panel.
This is all because of the port number issue. So follow the respective steps to overcome the problem.

Step 1 - From the XAMPP Control Panel, under Apache, click the Config button, and select the Apache (httpd.conf).

Inside the httpd.conf file, somehow I found a line that says:

Listen 80

And change the 80 into any number / port you want. In my scenario I’m using port 8080.

Listen 8080

Still from the httpd.conf file, I found another line that says:

ServerName localhost:80

Change 80 to 8080.

ServerName localhost:8080

Step 2 - From the XAMPP Control Panel, under Apache, click the Config button again, but this time select the Apache (httpd-ssl.conf). Inside the httpd-ssl.conf file, find line that says

Listen 443

And change the 443 into any number / port you want. I’ll using 4433 as the new port number.

Listen 4433

Still from the httpd-ssl.conf file, find another line that says

<VirtualHost _default_:443>

ServerName localhost:443

And change 443 to 4433.

<VirtualHost _default_:4433>

ServerName localhost:4433

Remember to save the httpd.conf and httpd-ssl.conf files after performing some changes. Then restart the Apache service.

Now everything will work fine.
