If I go to https://ipfs.io/ipfs/QmZAzWzyPXfM7q69USzffmBJGWB7o1PYmC1QjGGFZTWA1p, the file exists. I can see it on my local IPFS nodes too. I have it pinned locally + with Pinata and ipfs-pin.
The file also loads locally, in my web app, when working on localhost. But I have found that loading it from a hosted site - e.g. Github pages, or deployment with IPFS & Fleek can take minutes or not at all.
Not being able to load the file also happened on a different computer, on the same local network as the one I was doing the development on.
Is there something obvious that I have missed or I should look at?
(aside from pinning files on even more nodes)
