I have iCloud photo library enabled on my iPhone (6, iOS 8.3).
Since the weekend it does not upload the photos anymore.
When I go to the Photos settings, it gives me the following messages in a loop:
2324 Objects waiting for upload
Uploading 2324 objects
The progressbar shows up, fills up to around 30%, then disapears again. I translated the messages from German, they might be different when iOS is set to English. A restart of the phone does not help.
When I go to iCloud.com the photos are not there and also in Photos on my Mac I cannot see them. However when I create a shared album, I get the photos on Photos on my Mac.
