I'm trying to download the originals of some images, but the site periodically gives an error and does not allow me to download it.
You know, that reminds me. I see this a bit too.
Extremely infrequently, but sometimes attempting to download the original image gives me arbitrary error messages (500, 401, or sometimes just never responding to the request, etc). Say, I'll download p123 fine, p124 will give me an error, p125 will work fine, a retry of p124 will fail identically, etc.
Can't really reproduce it on-demand or share any links, because it solves itself after a while. I'll see it happening, go "oh it's that again", toss it into a bookmark and move on. And then come back an hour later and it will work instantly on the first try. Delete bookmark and go on with my life.
The site switched to serving some originals via H@H somewhat recently, right? If memory serves? I feel like that's what's going on here. Sometimes the H@H servers don't work right (for whatever reason), and the image load fails. That's just kinda how it works - the price paid for outsourcing to the H@H network, and it's understandable.
For resized images, we've always had the "reload broken image" button for cases when a particular H@H server wasn't working right. But there never was an equivalent for originals, since they were served directly from EH, right? Which presumably had high enough uptime/reliability to not need it. Now though, since originals may be served from H@H, you're dependent on their reliability (or lack thereof) there too - and there's no equivalent "reload broken image" for when it fails.. You're just kinda stuck with that one single link, and if it doesn't work, then sucks to be you.
...I mean, it's probably not exactly the highest priority issue. The site kind of discourages using originals via that button anyway, it solves itself after a while, and you could always just download the archive proper. Or torrent. But it's worth noting I guess. Hopefully there's some way to allow users to fall back to the main servers upon H@H failure (preferably in some way that doesn't get abused, as I assume moving it to H@H was done to reduce these kinds of downloads on the main servers anyway.)
