服务器数据库密码失效

import mysql.connector
from mysql.connector import errorcode

def connect_to_database(host, user, password, database):
    try:
        cnx = mysql.connector.connect(user=user, password=password, host=host, database=database)
        print("Connected to database successfully!")
        return cnx
    except mysql.connector.Error as err:
        if err.errno == errorcode.ER_ACCESS_DENIED_ERROR:
            print("Something is wrong with your user name or password")

            print("Database does not exist")
        else:
            print(err)

# 示例用法
host = 'localhost'
user = 'root'
password = 'your_password'
database = 'your_database'

cnx = connect_to_database(host, user, password, database)
if cnx:
    cnx.close()
