The player works perfectly here in China, but....
The Bot check is performed by Google which is blocked here, meaning that you need a VPN to pass the bot check. Using a VPN here is a game of cat-and-mouse, the government blocks the vpn, the vpn finds a work-around, the government blocks the work around - lather, rinse, repeat...
If you used a bot check (like Cloudfare) that isn't blocked here, it would make your player much more available in this market - as many people here don't have a vpn.
