When using twitter on my mobile and connected to my WIFI at home I noticed the images are not loading in the twitter mobile app
When turning off pi-hole the images are loading. But nothing was blocked in the query log.
I whitelisted twimg.com and twitter.com The issue was still there
When logged in to Pi hole I start an audit to see what pi-hole is doing realtime
I noticed allot of
NODATA-IPv6 when using twitter. All Cloudflare IPv6 DNS requests
Then it hit me. Recently I had to push a new config into my Unifi gateway. This activated IPv6. I have 2 external IP addresses one IPv4 and one IPv6
I changed my Upstream DNS in Pi-hole. I had Cloudflare IPv6 on and disabled it and activated the google one
I now have the following.
All is working again
