Amazon CDN question

Hello,

recently I got loads of website hits originating from China (got no customers from there). So I have enabled CDN service from Amazon cloudfront. Cdn is enabled and tested, it seems to be setuped correct.

Using amazon service against bots to block and geolocation block by country.

I have also tawk chat installed on website so no matter all set above tawk monitor shows 10 - 70 one page hits by some random ipv6 China ip, also developer resource monitor shows hi use of resources like cpu, network and memory even I got very minimum customs in holiday months.

Amazon charged me nearly 100eur for a month of their service. So how do these hits enter the site that tawk is showing as online?

So I’m not the only one! Wonder why the sudden uptick in visitors from China?

Have absolutely no clue
