Cannot create fs: unspecified error
Author: ConnorMcFCreated Dec 14, 2022Updated Jun 21, 2026
WinFsp seems to fail to create a filesystem with a vague error.
How to Reproduce
Interacting with anything that uses WinFsp fails.
rclone.exe mount user@host X:
2022/12/14 20:36:57 NOTICE: Config file "C:\\Users\\XXX\\AppData\\Roaming\\rclone\\rclone.conf" not found - using defaults
Cannot create WinFsp-FUSE file system: unspecified error.
2022/12/14 20:36:57 ERROR : Local file system at //?/C:/Users/XXX/Downloads/rclone-v1.60.1-windows-amd64/rclone-v1.60.1-windows-amd64/user@host: Mount failed
2022/12/14 20:36:57 Fatal error: failed to mount FUSE fs: mount stopped before calling Init: mount failednet use X: \\sshfs\\\user@host
The password is invalid for \\sshfs\\\user@host.
Enter the username for 'sshfs': user
Enter the password for sshfs:
System error 67 has occurred.
The network name cannot be found.net use X: \\memfs64\test
System error 67 has occurred.
The network name cannot be found.(memfs64 did not generate any event logs)
The event log contains the following logs when trying to connect via net use or rclone:
INFO launcher-x64: create sshfs\\\user@host = 0
ERROR sshfs: Cannot create WinFsp-FUSE file system: unspecified error.
INFO launcher-x64: terminated sshfs\\\user@hostBehaviors
WinFsp should be expected to create the filesystem.
Environment
- OS version and build:
10.0.19044 N/A Build 19044 - WinFsp version and build:
2022.2 1.12.22301 - SSHFS version:
