Amazon being blocked by threat intelligence feed?

Having the same issue. It says it's blocked and then says it's unblocked but ultimately goes back to being blocked again.

My initial thought was that my Hosts file got corrupted. I checked the Hosts file, but it was untouched. Maybe a virus? I scanned my computer with three bootable AV's but they found nothing. I'm now at the limit of my knowledge of networks. I'm hoping that it's NextDNS. But the question remains - is there a problem in the middle? NextDNS - Please support this issue ASAP. Thanks!

Having the same issue. Looks like a NextDNS is blocking an AWS Cloudfront URL (probably something getting hosted maliciously there) but it's inadvertently blocking all of Amazon.com in the process.

I'm also having the same issue

No problem here. 

Seems to be solved 

Eventually it is still happening.

Not all Amazon, but approximately every other query.

Do I need to disable the whole NextDNS or just some settings?

there is a useful bug report: https://help.nextdns.io/t/x2hn7lv/www-amazon-co-jp-blocked

The recommended is to whitelist every host ...
