IP address blocked

I have a lightsail instance running in Mumbai, I have installed Wireguard VPN on it and it works perfectly well, but some websites don't work with it, for example www.watch.tataplay.com But if I use my home broadband (from Jio) it works well. I understand that previously, many commercial VPN providers were using your servers, but since last year all them have stopped using Indian servers (due to change in law - Indian Computer Emergency Response Team, or CERT). So why is your IP address still blocked by many Indian streaming websites ? Please advice and help.
