Selenium无法发现打开的页面

我正在为我的项目使用web抓取，它在windows系统上运行得很好。在ubuntu上部署它在第一次运行我的脚本时运行得很好，但之后的任何时候我都会收到错误

selenium.common.exceptions.WebDriverException: Message: unknown error: unable to discover open pages

通常在此之前，脚本在返回错误之前大约有1分30秒没有输出。任何帮助都将不胜感激！
我的代码：

import selenium
from bs4 import BeautifulSoup, NavigableString
from selenium import webdriver
from selenium.webdriver.chrome.options import Options

for i in range(5):
    URLS = []
    URLS.append('https://website.com/')

for i in range(1):
        options = webdriver.ChromeOptions()
        options.add_argument("--no-sandbox")
        options.add_argument("--headless")
        options.add_argument("start-maximized")
        options.add_argument("window-size=1900,1080")
        options.add_argument("disable-gpu")
        options.add_argument("--disable-software-rasterizer")
        options.add_argument("--disable-dev-shm-usage")
        options.add_argument('--remote-debugging-port=9222')
        options.add_argument('user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.75 Safari/537.36')
        driver = webdriver.Chrome(executable_path="./drivers/chromedriver", options=options)
        driver.set_page_load_timeout(2)

        for url in URLS:
            try:
                webdriver.get(url)

                innerHTML = webdriver.page_source
                soup = BeautifulSoup(innerHTML, "html.parser")

                for i in soup.select("#ELEMENT"):
                    global ELEMENT
                    ELEMENT = i.text
                    print(ELEMENT)

                webdriver.close()
                webdriver.quit()
           

            except:
                pass

如果你想刮限制或封锁的网站，你必须使用随机用户代理。你可以检查下面的代码片段。希望它应该为你工作。

import random
import selenium
from bs4 import BeautifulSoup, NavigableString
from selenium import webdriver
from selenium.webdriver.chrome.options import Options

for i in range(5):
    URLS = []
    URLS.append('https://google.com/')

for i in range(1):
    user_agent_list = [
      'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36',
      'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:90.0) Gecko/20100101 Firefox/90.0',
      'Mozilla/5.0 (Macintosh; Intel Mac OS X 11.5; rv:90.0) Gecko/20100101 Firefox/90.0',
      'Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36',
      'Mozilla/5.0 (Macintosh; Intel Mac OS X 11_5_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36',
      'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:90.0) Gecko/20100101 Firefox/90.0',
      'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36'
    ]
    user_agent = random.choice(user_agent_list)

    browser_options = webdriver.ChromeOptions()
    browser_options.add_argument("--no-sandbox")
    browser_options.add_argument("--headless")
    browser_options.add_argument("start-maximized")
    browser_options.add_argument("window-size=1900,1080")
    browser_options.add_argument("disable-gpu")
    browser_options.add_argument("--disable-software-rasterizer")
    browser_options.add_argument("--disable-dev-shm-usage")
    browser_options.add_argument(f'user-agent={user_agent}')
    web_driver = webdriver.Chrome(options=browser_options, service_args=["--verbose", "--log-path=test.log"])

    for url in URLS:
        try:
            web_driver.get(url)

            innerHTML = web_driver.page_source
            soup = BeautifulSoup(innerHTML, "html.parser")

            for i in soup.select("body"):
                global ELEMENT
                ELEMENT = i.text
                print(ELEMENT)

            web_driver.close()
            web_driver.quit()
       

        except:
            pass

请让我知道它不工作。
