Summary of the issue you are facing:
I’m trying to sync my photos, screenshot and documents folder from my new brand Nothing Phone 3a pro to manage it with my Debian 13. I can see the folders, i can sync the files from the phone but when i trying to manage on my PC the didn’t sync and says:
I have reconstruct the nexcloud container from scratch, i’m using the official container. I have reinstall Debian, and the android app. I have manage permissions and i’m facing this all the time. I have notice it sync the first time i change the folder name, but just this time after i have the same issue.
The files seems to be on the server, at least i can see them. But, when i try to download the server says: the file is not on the server and it disappears.
Log entries
I don’t have any log of this. I just have this advertising on the desktop client. I can paste the logs of the entire server if needed but i don’t see the point, since there are no info on them.
