Cached image url not deleting even after ttl expiry

Deleted images from cdn, but after 3+ weeks, the images are still visible on some IP addresses even after clearing browser cache. Edge cache TTL max = 1 hour.

What happens is that sometimes it is 404, and upon changing ip address it comes back again.
It is definitely location dependent.

Please check ivdaniel22 account Cloudflare, he complains of the same problem.

In fact i even had a problem with modification of url, but upon further request admin ‘deleted’ the image to the point where modifying the url no longer works

BUT

the image still comes back in certain locations after 4 weeks, despite edge cache ttl max = 1 hour. admin has no explanation.

please someone familiar diagnose this godforsaken issue
