Google DNS?
UAE has banned VPNs with very strict fines if caught. Proceed with caution. PIA didn't work for me in Dubai, when I was there a few months ago.
Smart DNS worked for me a few months back. Use their free trial and see if it still works
Getflix/Smart DNS Proxy should be enough to bypass that geo restriction.
IPVanish has servers in UAE and India both if that helps
Smartdnsproxy.com
Works best
Surfshark is quite good at bypassing geo-blocking and I used it while I was in UAE month ago, I guess it should still work. Heres the VPN if you haven't heard about it https://surfshark.com/
Hotstar works fine with most vpn for me on firestick - have tried windscribe, express, vpn unlimited. However amazon prime india blocks all VPN's so still haven't found one which works with it.
If you use ErosNow the VPN won't be necessary as it's legal.
