why does no python socket port 5555 t work

Question

i'm tring to test some online game with socket, and i'm getting error in the line of s.bind((my ip, the port)) when i use the port (5555), but when i use a dهfferent port (4444) the error does not appear, even thouth the same (5555) port was working at first, so, is there any way to fix the error of the port (5555) or i just have to use another port? thanks, and this is my server code(it's not completed yet).

import socket as sct
import _thread as trd
import sys
from colorama import init, Fore
init(autoreset=True)

server="192.168.43.222"
port=5555
s= sct.socket(sct.AF_INET, sct.SOCK_STREAM)

def info(color:str, title: str, msg:str =None): 
    if color=='red':
        f=Fore.RED
    elif color=='blue':
        f=Fore.BLUE
    elif color=='green':
        f=Fore.GREEN
    elif color=='cyan':
        f=Fore.CYAN
    elif color=='magenta':
        f=Fore.MAGENTA
    elif color=='yellow':
        f=Fore.YELLOW
    print("[", end="")
    print(f+title, end="")
    if len(title)!=13:
        d=13-int(len(title))
        for l in range(d):
            print(" ", end="")
    if msg!=None:end=''
    else:end=None
    print('] ', end=end)
    if msg!=None:
        print(msg)
