Can’t open Amazon.co.uk in UK

Same here, definitely being blocked on www and on app.

Android 

Same. amazon.co.uk isn't working. But it works if I used Cloudflare DNS or my ISP DNS.

The logs are showing that Google Safe Browsing is blocking a CDN being used by amazon.co.uk. Adding amazon.co.uk to your NextDNS Allowlist settings solves the problem.

Same here, started today. Glad it's not just me. 

Amazon UK is also blocked for me as well, iOS app and Safari. Blocked on the PC as well as I have the router configured to use NextDNS. As soon as I disabled NextDNS Amazon UK worked immediately on every platform. 
 

Started yesterday where it would work ok, fail for a few minutes then work again, today though it's permanently blocked at the moment.

Same. Says it's being blocked by google safe browsing. Very annoying. 

I had to add to Allow List, re-install NextDNS certificate, and then it worked and I could remove from Allow List. Back to normal ops.
