Mounting External Storage

So I’m running into a small speedbump in my nextcloud install:

I’m using the External Storage support app on nextcloud itself.
I have a NAS SMB share and a Windows server 2016 SMB Share.
When I mount the NAS storage I have 0 issues everything is smooth.
When I try to mount the windows server share it won’t work.
Samba client is installed, cfutils are also installed.

Nextcloud 21.0.1
Ubuntu Server 20.04

[no app in context] Warning: External storage not available: Unknown error (NT_STATUS_OBJECT_NAME_INVALID) for /PUT /nextcloud/index.php/apps/files_external/globalstorages/1


Icewind\SMB\Exception\Exception: Unknown error (NT_STATUS_OBJECT_NAME_INVALID)

Is there anyone that has the same issue? Or maybe fixed this?
