Точки монтирования сервера samba перестали работать при установке CentOS 8, ошибка: не удалось запустить обработчик SPNEGO для списка OID negprot

Примерно через 6 месяцев безупречной работы smb на домашнем сервере, теперь он не может разрешить подключение удаленных систем со следующим сообщением об ошибке в / var / log / messages:

Jun 27 12:53:10 bike3 smbd[19385]: [2020/06/27 12:53:10.706872,  0] ../../source3/smbd/negprot.c:211(negprot_spnego)
Jun 27 12:53:10 bike3 smbd[19385]:  Failed to start SPNEGO handler for negprot OID list!

Я использую очень простую конфигурацию smb.conf и безуспешно пробовал различные настройки в Google:

[global]
        workgroup = WORKGROUP
        security = user
        log level = 3
        map to guest = bad user
        dns proxy = no
; tested various combinations:
        client use spnego = no
        client ntlmv2 auth = no
        client min protocol = SMB2
        client max protocol = SMB3


[pictures]
       comment = pictures
       path = /mnt/pictures
       public = yes
       browsable = yes
       writable = yes
       guest ok = yes
       read only = no

Я переустановил все пакеты самбы:

Reinstalled:
  samba-4.11.2-13.el8.x86_64                  samba-client-4.11.2-13.el8.x86_64            samba-client-libs-4.11.2-13.el8.x86_64      samba-common-4.11.2-13.el8.noarch
  samba-common-libs-4.11.2-13.el8.x86_64      samba-common-tools-4.11.2-13.el8.x86_64

Я тестировал Windows 10 и OS X Mojave, оба не работают с той же ошибкой, вот уровень журнала 3 в log.smb:
