update, i was able to fix it
after googling a bit i found this:
SMB mount error(112): Host is down
now i have to use these options:
user=***,password=***,_netdev,sec=ntlm,iocharset=utf8,vers=1.1
i now have to specify the version to mount my smb share
yesterday i performed a apt-get upgrade on the raspberry, so i had complete clean upgraded version
i guess after the upgrade the raspbian has a new smb version, so now i have to specify hich version i want to use
in my case i need to specify version1.1 to be able to mount the share
version 2 gives me the same mount error 112
