Selenium doesn't open website with provided url (url is valid)

I try to open whois EURID website with no luck. Selenium opens browser (tried with Chrome and FF), but when I try to open particular URL (http://whois.eurid.eu/):

nothing opens, I got blank page only.

I have driver set by this function:

    def set_driver() -> WebDriver:
        service = Service()
        if cfg["browser"]["browser_name"].strip().lower() == "firefox":
            options = webdriver.FirefoxOptions()
            driver = webdriver.Firefox(service=service, options=options)
        elif cfg["browser"]["browser_name"].strip().lower() == "edge":
            options = webdriver.EdgeOptions()
            driver = webdriver.Edge(service=service, options=options)
        else:
            options = webdriver.ChromeOptions()
            driver = webdriver.Chrome(service=service, options=options)
        return driver

Using driver (set above) I try to open webiste and scrape some data (information about domain):

    domain_name = "ddddddd.eu"  # any name ending with '.eu'

    URL = f"https://whois.eurid.eu/en/search/?domain={domain_name}"

    drv = set_driver()
    drv.get(URL) 
    time.sleep(5)

I think this website is currently somehow protected, as I have had no problems with opening it before.

Cloudflare Protection or User Agent Detection or JavaScript might cause the issue.

Please find below an enhanced solution for your consideration:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

def get_eurid_whois(domain):
    chrome_options = Options()
    chrome_options.add_argument("--start-maximized")
    chrome_options.add_argument("--disable-blink-features=AutomationControlled")
    chrome_options.add_argument("--disable-infobars")
    chrome_options.add_argument("--disable-extensions")
    chrome_options.add_argument("--disable-popup-blocking")
    chrome_options.add_argument("user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) "
                                "AppleWebKit/537.36 (KHTML, like Gecko) "
                                "Chrome/122.0.0.0 Safari/537.36")

    driver = webdriver.Chrome(service=Service(), options=chrome_options)

    try:
        url = f"https://whois.eurid.eu/en/search/?domain={domain}"
        driver.get(url)

        time.sleep(3)

        try:
            WebDriverWait(driver, 15).until(
                EC.presence_of_element_located((By.CSS_SELECTOR, ".btn"))
            )
        except:
            print("Page didn't load properly. Check if blocked by CAPTCHA.")
            return None

        try:
            register_button = driver.find_element(By.XPATH, "//a[contains(text(), 'Register now')]")
            print("Domain is available. 'Register now' button found.")
            return "Available"
        except:
            print("Domain is not available. 'Register now' button not found.")

        whois_data = driver.find_element(By.CSS_SELECTOR, ".btn").text
        return whois_data

    finally:
        driver.quit()

print(get_eurid_whois("ddddddd.eu"))
