Artix Linux - "Failed to open. no permission to access folder" when opening vault from external server

Help

What I’m trying to do

Open Obsidian vault located on external home server, mounted in root directory /mnt/ - Whenever I try to open the folder using Obsidian, I get the “Failed to open. no permission to access folder” popup.

This setup works flawlessly in Windows, & has worked on other computers in the past with little issue.

Things I have tried

  • Installed Obsidian through Flatpak (latest update 1.12.7) and adjusting folder permissions through Flatseal (allowed /mnt/, allowed all system file permission)
  • Disabled fast-boot in Windows (shuts down Windows instead of hibernating, which sometimes causes issues)

Tried user permission?

I’m running as sudo, and Obsidian should have all necessary permissions on it’s end. Chmod won’t let me edit read-write permissions for individual folders (I’m guessing due to how the server partitions are formatted), however I gave @everyone full control over the entire SMB share (temporarily, for testing) and nothing changed.

All I remember is downloading and unzipping demo vaults on (iOS? Linux?) and not being able to write to files unless I changed permission to “user”.
Not sure this is the same general problem.
