iOs 8.4 Photos no longer upload to iCloud

My iCloud Photo Library was stuck for 2 days uploading. As recommended in this post I deleted the photos I had in the recently deleted album folder and that fixed the problem. Thank you!!

Thank You. Deleting and then emptying recently deleted got things going again for me. 6 plus on 8.4

Still hasn't helped me.. I've tried multiple things, including signing in and out of iCloud, deleting all recently deleted photos, making sure I have over 300mb of free device storage, charged above 20% connected to WiFi, payed for 20GB of extra iCloud Storage and rebooted.... Still will not upload any photos! It says it is, and the progress bar appears and disapears in a millisecond. HELP!

Try this it worked for me:

Backup iPhone

Do an iPhone Restore

Restore Backup

Then delete photos in "recently deleted" photo album

Good Luck!!

Does anyone know what causes this issue? And how we can prevent it in the future? it seems as if this needs to be addressed to the apple software team. i brought this to the apple care specialist and he couldn't help me, he said "it looks like you've tried everything I would of tried". And then that was it. No real answer As to why this happens... We need some help Apple! Please fix this issue and give us more control over when and how our photos sync. We need a button in settings to invoke the sync like a stop/restart button Or even pause/continue. - Everyone That Uses iCloud Photo Library

What worked for me was switiching iCloud Photo Library off. This triggers deletion of photos on the phone. This may take some time. Let it continue. Photos not yet uploaded will stay on the phone and won't be deleted.

Do not delete any albums. They will be empty, but leave them there. If you do delete them, they will also be deleted from your photo library once you switch it back on.

Once the cloud photos (or thumbnails) have been deleted, reboot your phone and switch Photo Library back on. The phone will start downloading thumbnails (or full size photos if you prefer). This may take some time. Any photos not yet uploaded will be uploaded. No data will be lost.

I was able to narrow down the problem to a WiFi connection that requires a login first, like in a hotel. The phone tries to connect, but can't due to the login. That then stalls the process.

I have had similar problems and can also link to a hotel with password required and a cafe wifi which required a password. Fixing it is another issue again...
