Can urlopen be blocked by websites?

[peterjv26]

Hi, I am trying to scrape a web site with following code. But it comes with a Timeout Error as below.

TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

If I try with other websites, it works.
Wondering if sites can block urlopen?
Is there any way around?
Appreciate any help.

from urllib.request import urlopen
from bs4 import BeautifulSoup

url = "https://www.nseindia.com/option-chain"
html = urlopen(url)

soup = BeautifulSoup(html,'lxml')
type(soup)

title = soup.title
print(title)
