Checking for open ports in python

I am learning hacking from this tutorial on youtube. Around 1:11:30 (timestamp), he tries to check for open ports on the ip of his own router and on http://testphp.vulnweb.com. He gets 4 ports as open for each. When I run my code I only get port 80 open on my router and none on http://testphp.vulnweb.com.

This is my Code:

import socket
from IPy import IP


def check_ip(address):
    try:
        IP(address)
        return address
    except ValueError:
        return socket.gethostbyname(address)


def scan(target):
    ip_address = check_ip(target)
    print(f"\n[-_0 Scanning Target] {str(target)}")
    for port in range(1, 100):
        scan_port(ip_address, port)


def scan_port(ipaddress_, port_):
    try:
        sock = socket.socket()
        sock.settimeout(0.5)
        sock.connect((ipaddress_, port_))
        print(f'[+] Port {str(port_)} is open')
    except:
        pass


targets = input("[+] Enter Target(s) to scan (split multiple targets with , ): ")

if ',' in targets:
    for target in targets.split(','):
        scan(target.strip(' '))

else:
    scan(targets)

And this is the output:

[+] Enter Target(s) to scan (split multiple targets with , ): 192.168.1.1 , testphp.vulnweb.com

[-_0 Scanning Target] 192.168.1.1
[+] Port 80 is open

[-_0 Scanning Target] testphp.vulnweb.com

So, where am I going wrong? Is it a problem with my connection? my code? or is this normal, and if it is then why is the guy on youtube getting a different result?

Any help is greatly appreciated!
