Trouble with Samba shares on old Blu-Ray player since December update

Well I believe we are all no Samba experts and can mainly guess. But for me this looks like either really wrong password used or the password security protocol issue. I would suggest the following:

  1. Set new password on OSMC with sudo smbpasswd -L -U osmc and then be 100% sure to use that password on your BlueRay player.

If that doesn’t solve the issue allow weak password protocol

  1. sudo systemctl stop samba
    sudo nano /etc/samba/smb.conf
    add the line lanman auth = yes and ntlm auth = Yes
    sudo systemctl start samba
