there was an error downloading this photo from your iCloud photo library

EASY FIX:

go to settings > Account > icloud account > photos > check off "download and keep original photos" and uncheck "optimize photos".

That should do it, but it will take some time for the iphone to actually download all the photos. make sure your on wifi and that your not running battery saver. restart your phone atleast 1 time.

What worked for me is the following: I had Paused the uploading/sync’ing of photos to iCloud from the Photos tab of the app. After I “Resumed” it and once it finished uploading, I was able to download pictures that were stored in iCloud and which I had only the thumbnails. Worth a shot.

i Just had this issue because cellular data was off for downloading photos, and my Wi-Fi was off. Seems obvious but because the error message was so generic it took me a very long time to sort it out.

I experienced the same problem, I tried all suggestion in this thread but nil result.

then I just figure it out, try downloading photo/video from icloud to iPhone library using wifi connection. When I use my local provider, the error notice came out to download but once I use wifi is no problem.

sorry if my english is not good.

thank you

They posted the fix go to general settings and turn off low battery mode, maybe a soft reset for you hold down home button and side button but for me turning off low battery fixed my issue

THIS. This is the solution. Turn off “Low Power Mode” in Settings -> Battery .. Things started downloading successfully after this was turned off. Start with this solution.

I’ve had this issue for a while now, this wasn’t happening to all my photos but a few random ones. I tried everything suggested, turning off and on again, clearing up space on iCloud, switching it to download and keep originals but nothing worked and I have finally managed to fix it. I downloaded iCloud for windows and saved all my photos. Then emailed myself the problematic images, saved them to my phone and now I have the full resolution original images and am able to edit them with no problems. Hope this helps someone x

Awesome thanks. I turned off low battery and now it will download. I woul Buy you a beer 🍺 if your local.

It's because the LOW BATTERY MODE, just deactivate it, you don't even have to have your phone plugged in.

For me: it looks like it's working now that i have "low power mode" no longer on.

I tried logging into iCloud Photos from my computer but it keeps saying network is taking too long to load.

Resolved this by enabling “Settings > iCloud > Photos > Upload to My Photo Stream”.

May have to wait a few minutes for the photos to sync before the error indicator disappears.

It is easy! Just disable to turn OFF the Low power mode!

It is not about Icloud setting!

On my side this is what have fixed it!

THIS!!!! Low battery mode. Ding ding ding!!! I’ve taken to keeping my phone in LBM at all times now. Never even thought about that. Thank you!!!

So, no solution for this? Tons of people seem to have this problem and I've never seen a solution that anybody has said worked for them. All I know is that Apple has put all my photos into low-res **** since I started using iCloud, and I can't get them back. I've reset, logged out and in, etc. Still get "Cannot Download Photo". Seems like this ought to be simple. I take pictures, Apple uploads a copy to the cloud, fuzzes up my local copy, and when I want it back it should just happen. So why doesn't it?

I doubt any of your media would have been deleted by following the steps of those previous posters. Most likely the media has been deleted from you iPhone if icloud photo library was enabled. By signing out of your Apple ID in icloud you will automatically disable icloud photo library. Once you re enable icloud photo library all your media will be gradually restored again from icloud.com. Don't worry about anything being lost.

If you didn't have icloud photo library enabled, the media would remain in your camera roll. When icloud photo library is turned off, the camera roll will reappear in the photos and camera apps. Any third party apps you've granted permission too from the app store may also display the camera roll. Once icloud photo library is re enabled, the camera roll will disappear and be replaced by an album in photos called All Photos. Wait awhile shortly after turning on icloud photo library after signing into icloud in settings again with your Apple ID credentials. Everything will gradually restore at varying speeds depending on your WiFi network speed. You must use WiFi to restore any media such as photos and videos from icloud to your phone or other iOS device. You cannot restore anything over a celluar mobile network.

Even if you icloud photo library was nerve turned on the media would have been backed up within the camera roll to icloud with your other iPhone data. With the camera roll replaced by All Photos while icloud photo library is activated, the media will not be backed up twice with icloud photo library and the iPhone icloud backup. To conserve space and prevent duplications, Apple has removed the camera roll for users using icloud photo library. I think the major downside with using icloud photo library has been the impracticalties. Either your photos and videos are everywhere on all Apple devices or they're not where at all. If you move a photo or video to recently deleted while icloud photo library is turned on with one device, exactly the same change is replicated everywhere else on other devices using the same icloud photo library.

Simply following those steps above by other posters could not have possibly resulted in any data lose. You literally would have had to wipe your iPhone without doing any backup or manually delete everything individually. No previous poster instructed you to perform any of those actions. I do not believe you have lost anything. If you hate the icloud library feature, I could not really blame you. Space is conserved on devices with lower storage by using the optimise your storage feature in Photos settings with icloud photo library. There is really no need to everbdelete a photo or video for saving space while using icloud photo library is enabled if you're using optimise your storage. This saves space anyway. If people didn't want to see something, they could hide the photo or video. Once again, all changes occur within the centralised icloud photo library database. Hide an item on one device, you will find it hidden on every device. These are the issues one must be forced to endure by using icloud photo library.
