Why IntelliJ IDEA doesn't not stop at breakpoints when using PHP and Xdebug?

Question

Thanks for taking the time to read through my post. I am trying to debug a Laravel application in IntelliJ Idea. I've configured everything required. Using Visual Studio Code I was able to break on a point, read variables, and such. However, IntelliJ Idea doesn't seem to work and stop on a point. The following are all my configurations:

1. Out put from php --version to that Xdebug is configured.

PHP 8.0.5 (cli) (built: Apr 29 2021 15:56:40) ( NTS )
Copyright (c) The PHP Group
Zend Engine v4.0.5, Copyright (c) Zend Technologies
with Xdebug v3.0.4, Copyright (c) 2002-2021, by Derick Rethans
    with Zend OPcache v8.0.5, Copyright (c), by Zend Technologie

2. php.ini Xdebug configurations:

[xdebug]
zend_extension="/usr/local/lib/php/pecl/20200930/xdebug.so"
xdebug.mode=debug
xdebug.client_host=127.0.0.1
xdebug.client_port=9003
xdebug.log = "/Users/my-name/php-debug/xdebug.log"

3. Screenshot to show that Xdebug Extension is installed in Chrome.

4. IntelliJ IDEA Configurations:

5. I tried to troubleshoot Xdebug by using a log file here are the logs when I call http://localhost:8888 in my browser.

Answer 1

Ok, the problem was that in "ignore external connections through..." this tick should not be selected. as in the picture bellow.
