Issue with Option Chain Page with NSE after 3PM on 19-AUG-2022

Hi,

I am checking option chain on NSE Site, but it’s showing another page of NSE after 3PM on 19-AUG-2022.

option Chain link- https://www.nseindia.com/option-chain

https://www.nseindia.com/get-quotes/derivatives?symbol=NIFTY

Above link routing to other NSE Web page as below.
Let me know what can be reason for this as option chain page is routed to old NSE website currently and unable to access NSE official Option chain web page.
