Steps to reproduce

1. Do something with the contents of an encrypted folder (in my case I added a bunch of files to the folder, where some files were identical to existing files, except having an earlier timestamp, which I explicitely used to overwrite existing files, essentially making some of the files inside of encfolder younger), otherwise what exactly triggers this is unknown
2. Put new file into folder, if new files were already added in 1, that seems to be enough
3. Wait for upload action of nextcloud-desktop
4. Server will respond with 403 Forbidden
5. remove new file, unsync "encfolder", wait for sync action to delete folder locally
6. add folder back to synced folders and wait for it to fully synchronize
7. GOTO: 2. and see no change

Expected behaviour

File is uploaded. If any error is related to some client stuff, unsyncing the folder and having it resync again should have cleared that out.

Actual behaviour

File is rejected, as folder seems to be locked no matter what

[MrRinkana]

Wouldnt this be a client issue? I don't see how the server would see any difference between a new file and overwriting an existing with new timestamps
