Running python script with shell_exec() in php script results in permission denied error

I am connected to my OracleLinux server via an SSH connection. The server is running a working apache webserver and also php. Python3 is also installed.

Now I am currently trying to run a php script via a JavaScript AJAX request to in turn run a Python script with it.

Directory structure:

/var/www/website/webwatcher
--index.html
--js/
-----script.js (run PHP script from here with AJAX request)
--php/
-----getWebsiteElementValue.php (run webscraper.py from here)
--python/
-----webscraper.py

script.js:

window.onload = () => {
    
    getWebsiteElementValue((data) => {
        console.log(data);
    });
}

function getWebsiteElementValue(success) {
    let ajax = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject('Microsoft.XMLHTTP');
    let ajaxURL = '/webwatcher/php/getWebsiteElementValue.php';
    ajax.open('post', ajaxURL);
    ajax.onreadystatechange = () => {
        if (ajax.readyState > 3 && ajax.status == 200) {
            success(ajax.responseText);
        }
    }
    ajax.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
    ajax.send();
}          

getWebsiteElementValue.php:

<?php
    $output = shell_exec('/usr/bin/python3 /var/www/website/webwatcher/python/webscraper.py 2>&1');
    echo $output;
?>

webscraper.py:

from bs4 import BeautifulSoup
from urllib.request import urlopen
from sys import argv
import ssl

url = 'https://buyzero.de/products/raspberry-pi-4-model-b-8gb?variant=31817426698342';
cssSelector = 'div.product-form__info-list > div:nth-child(2) > div > span';

context = ssl._create_unverified_context();
page = urlopen(url, context=context);
html = page.read().decode("utf-8");
soup = BeautifulSoup(html, "html.parser");

elementText = soup.select(cssSelector)[0].text;
print(elementText);

When I run the python script via the terminal, it returns the desired output without error. However, when the same happens via the shell_exec() php command I get the following error messages (shortened) in the console of the website: PermissionError: [Errno 13] Permission denied and urllib.error.URLError: <urlopen error [Errno 13] Permission denied>

The /var/www folders both have the following permissions drwxr-xr-x. and belong to root:root. The directory structure of website/ up to the file webscraper.py (also all subfolders and files in it) belongs to apache:apache and has the permissions drwxrwxr-x. and -rwxrwxr-x. respectively.

Where is the error now?

@MaciejWrobel's comment brought me to the solution of the problem.

Because the httpd_can_network_connect boolean of the Linux system is set to off by default, it seems to prevent access to various Python modules in a Python script and ends up in the above error. Running the command setsebool -P httpd_can_network_connect on in the terminal fixed my problem.
