- We only accept bug reports that are reproducible with the installation methods we provide on our website. If you obtained Obsidian elsewhere, you MUST reproduce the problem with one of the officially supported installation methods (No ARCH, NixOS, homebrew, chocolatey, third party packages).
Once you’ve done the above, delete everything above this line.
Steps to reproduce
- On macOS, add a video file (.mp4 or .mov) into the Obsidian vault.
Example:
mp4/H579 I cannot breath of Thee.mov - Create a note with an embedded video link:
![[H579 I cannot breath of Thee.mov]] - Sync the vault from macOS to iPhone using Nutstore Sync plugin (WebDAV).
- Wait until synchronization is completed.
- Open the same note on Obsidian iOS.
- The embedded video shows “File not found”, although the video file exists in the vault.
- If I manually attach the same video file again on iPhone, the link works immediately.
- Alternatively, completely close Obsidian from the iOS app switcher and reopen it. After restart, the same link works normally without changing the markdown.
Did you follow the troubleshooting guide? [Y/N]
Please, follow the Troubleshooting Guide before answering Yes.
Expected result
After the synchronization is completed, Obsidian iOS should immediately recognize the newly synchronized video files in the vault.
The embedded video link:
![[H579 I cannot breath of Thee.mov]]
should be found and playable without requiring a manual re-attachment or restarting Obsidian.
Actual result
The embedded video link shows “File not found” after synchronization.
The video file exists in the vault and can be opened after manually attaching the file again or restarting Obsidian.
Environment
iPhone + iOS, Obsidian Mobile, macOS Obsidian Desktop, Nutstore Sync plugin via WebDAV.
The vault is synchronized successfully. MP3 files work normally, but MP4/MOV files require Obsidian restart or re-attachment before wiki links work.
Additional information
- The issue is reproducible consistently.
- The video files are successfully synchronized from macOS to iPhone.
- The video files can be seen in the Obsidian file explorer on iPhone.
- The problem is not related to video format, because both .mp4 and .mov files show the same behavior.
Comparison: - .mp3 files work normally after synchronization.
- .mp4/.mov files show “File not found” after synchronization.
Workarounds found:
- Manually attach the same video file again on iPhone. The link immediately works.
- Completely close Obsidian from the iOS app switcher and reopen it. The original link then works without changing the markdown.
This suggests that the issue may be related to file indexing or metadata cache refresh after external synchronization.
