Some internet url or IP are not reachable through Cloud Function

I tried to make some http requests through GCP's Cloud Function with Python 3.10 runtime, some went well, and some went wrong.

To find out the reason, I ping the IP of each url, and the IP I need has no response:

ping ip(173.194.217.106) of url(https://www.google.com): True

ping ip(69.147.92.11) of url(https://www.yahoo.com): True

ping ip(13.107.42.14) of url(https://www.linkedin.com): True

ping ip(117.56.7.114) of url(https://data.moi.gov.tw): False

Is there any way to make a successful request to https://data.moi.gov.tw through Cloud Function?

Here are the materials to reproduce the results with Cloud Function (Gen1):

main.py:

import platform    # For getting the operating system name
import subprocess  # For executing a shell command
import requests

def ping(host):
    """
    Returns True if host (str) responds to a ping request.
    Remember that a host may not respond to a ping (ICMP) request even if the host name is valid.
    """
    # Option for the number of packets as a function of
    param = '-n' if platform.system().lower()=='windows' else '-c'
    # Building the command. Ex: "ping -c 1 google.com"
    command = ['ping', param, '1', host]
    return subprocess.call(command) == 0

def main(event):
    d_ip_url = {
        '173.194.217.106' : 'https://www.google.com',
        '69.147.92.11' : 'https://www.yahoo.com',
        '13.107.42.14' : 'https://www.linkedin.com',
        '117.56.7.114' : 'https://data.moi.gov.tw',
    }

    for ip, url in d_ip_url.items():
        print(f'ping ip({ip}) of url({url}):', ping(ip))
