I suggest you read 'man smb.conf', you have a lot of default settings
and some that do not make sense because you are not using SMBv1.

If you do read 'man smb.conf' under 'server multi channel support' you
will find:

This boolean parameter controls whether smbd(8) will support SMB3

Now you have set 'client min protocol = SMB3' , but are you aware that
this refers to the client on the Samba machine and not any external
client ? There is another parameter 'server min protocol' which refers
to your samba server that others connect to and this defaults to SMB2.

Try setting 'server min protocol = SMB3' and see if that helps.
