unfortunately there’s one website where the pictures are not resolved properly - this is https://www.otto.de/.
Example picture is https://i.otto.de/i/otto/001_2019_12_mult_marke_bose_25052?$promo_poi_8-3_xl_progressive$
When directly addressing this picture, firefox shows “server not found” (similiar result with safari on iPhone 7 with lates iOS).
Disabling device level adblocker and no-script didn’t help.
My configuration is:
- Turris Omnia, TOS v.3.11.6
- adblock installed
- kresd resolver with following configuration:
- DoT to 188.8.131.52
- DNSSEC activated (ISP Deutsche Telekom)
- Connection test via Foris shows both DNS and DNSSEC as working
I had a similiar problem with pictures on zalando.de, which got resolved by adjusting adblock. But disabling adblock doesn’t help for https://www.otto.de/ (I even tried restarting the router afterwards).
