Twitter images blocked when NextDNS is on

Hi,

Using NextDNS, it happens often that twitter cannot load images. Disabling NextDNS fixes the issue.

On the logs, twitter and *.twimg.com domains are allowed, twitter requests are not blocked.

I've seen this problem is common in different forums, not only with NextDNS, but how to fix it ?

It sounds like one of your blocklists may be blocking a specific domain that Twitter needs. Have you tried turning off most of your blocklists to see what happens?

Doesn't look like it because I don't have any blocked query in the logs. That's the problem.

So why is NextDNS preventing twitter images from loading whereas I don't have anything blocked in the logs ? I soon as I disable NextDNS, the images load immediately.

I really like NextDNS but this is really frustrating.

I tried with the CNAME flattening on and off, it makes absolutely to difference. Twitter images won't load.

  JM yes, or make sure you don't have DNSSEC validation enabled on your client.
