Notify is not supported with the used smb version

Hello Guys, I am using nextcloud 14 on an ubuntu 18.04 server with your usual lampstack
everything is installed fine but now i need to mount a smb-share (Windows Server 2012R2)
I can mount it just fine in nextcloud BUT when I run

sudo -u www-data php occ files_external:notify 12 -u user@domain.local -p somepassword"

I always get the error “Notify is not supported with the used smb version”

could somebody help me out, please ?

any solution for that?
I have the same behavior
