External Storages Problem to Configure

Hello,

Ubuntu 20; ARM 64; Raspberry Pi 4; Snap Nextcloud.

In External Storages Web page:

Folder name = Samsung
External storage = Local
Authentication = None
Configuration = /srv/dev-disk-by-label-Samsung\040SSD\040860\040QVO

What’s wrong?

[PHP] Error: stat(): stat failed for /srv/dev-disk-by-label-Samsung\ SSD\ 860\ QVO/ at /snap/nextcloud/23500/htdocs/lib/private/Files/Storage/Local.php#148

GET /index.php/apps/files_external/globalstorages/2?testOnly=true
from 192.168.1.108 by nc at 2020-10-12T21:38:03+00:00

…and another attempt…

My /etc/fstab:

/dev/disk/by-label/Samsung\x20SSD\x20860\x20QVO /srv/dev-disk-by-label-Samsung\040SSD\040860\040QVO ntfs-3g defaults,nofail 0 2

Thanks in advance.
