RESOLUTION: Windows 10 Clients receive error "the parameter is incorrect" and can't access samba shares
https://access.redhat.com/solutions/296793
If you have windows 10 clients that can not reach a Red Hat Linux Samba share, consider the solution ID above.
It helped resolve the issue with a customer I work with.
In short, go to the [global] section of the smb.conf and add a line to that section max protocol = SMB2
and restart samba.
If needed, submit a case with Red Hat.

p.s. SMB1 shouldn't even be used IMO
