Description

Actual behaviour

A Folder inside the iOS Nextcloud App is empty.
Refreshing will not change the context (still empty).

Indeed there are files & folders in it.
The Web Application and the Windows 10 Nextcloud Agent - both will show files & folders properly.

no behave change on:

  • Restarting the iOS App
  • connect via Wifi or other networks

Other Directories (including their files) do work.

Increased Log verbosity on iOS App:

  • Status code 404 seeen
    (normally - 404 means, that the ressource cannot be found (dead links).
Steps to reproduce
  • not seen before
  • for that moment, single event for this directory
some Side Information
  • for this folder (with issues) - the offline availability was choosen once
  • Some weeks ago, an attempt was made to access this folder while the cloud was completely down, while the Flag "make available offline" was already enabled for this folder.
  • disabling the "make available offline" flag does not bring the desired effect. The folder remains empty.
  • BUT: set the "make available offline" Flag again in one of the empty folders, brings the files back and after unsetting
    the flag "make availabe offline" the files are staying at their place.
Expected behaviour
  • Sync agents should be up2date with their contents (Core-Cloud)

Research direction

Start with the iOS detailed log and the PROPFIND request to the affected WebDAV folder. Compare the successful 207 response with its property-level HTTP/1.1 404 entry, then reproduce the empty-folder behavior if possible using the stated offline-availability sequence. Done means the affected folder and its contents display correctly without requiring the offline flag to be toggled.
