We found the culprit - we think something was changed for our static/ folder.
We set up with the Customer Success team that we cache everything in Cloudflare:
In order to maintain fall-back for all our JSONs. Since JSONs are static assets and not related to ads, this folder was whitelisted for "Cache everything" instead of "Standard".
It seems this whitelisting has been disabled, because as soon as we disable "Cache Everything" Rule in Cloudflare we see a HIT on this JSON file from Ezoic CDN.
As this is not working as discussed during initial set-up and as intended, kindly whitelist "Cache everything" again for /static/ folder on your site.
The Technical Engineering team of Ezoic has approved this solution before, as it does not interfere at all with "Standard" caching for resources where ads are embedded.
Kindly update when the whitelisting is done again.
Thanks
