The issue you are facing:
I have auto upload configured on nextcloud App to upload to an external storage folder. For large files 100MB+ it will show the file uploading in transfers, the progress bar will complete and then it will upload again, and again and again. The file shows up via the nextcloud web console and makes it way to the external storage (s3). However, I have to manually stop the file from continuing to upload.
The log files do not show anything out of the ordinary (ios app logs and web logs)
Is this the first time you’ve seen this error? (Y/N): N
Steps to replicate it:
Take large video on phone (happens on iphone and android) - watch auto upload - continues to upload over and over
