smb.conf min protocol = Таймауты SMB2 с удаленного компьютера (в локальной сети)

Я попытался включить min protocol = SMB2 , чтобы повысить безопасность моих локальных машин Linux. Но когда я это делаю, я получаю тайм-аут из KDE и Operation Not Supported из CLI.

Удаление условия минимального протокола решает эту проблему. Есть идеи, почему?
