NET USE and ERROR 67

NethServer Version: 7.9.2009
Module: SMB

Hi
I moved one client from SME7 (old!) to NS7 and his access to VPN stopped working with ERROR 67 at net use command.
I cannot find anything wrong with VPN as HTTP pages works fine!
There are anything else I should care / test about NET USE mapping in NS7 ?
It worked for several years on SME7 (using VERY OLD SMB modules!), so I think it’s something about SMB configuration on NS7 that different from SME7.
BTW: I just saw this in on Win11, on Win10 I got at least ONE machine working.
