mount error(112): Host is down
Well, the host is definitely *up*: responds to pings and everything (from that very Debian machine). So it's gotta be something else.
I suspect SMB protocol changes/updates (as usual).
Thanks to a [blog post by "warlord0" in 2017], I've tried adding "vers=2.0" to my fstab entry:
That did the trick!//win10host/ShareName /mnt/win10host cifs uid=myuser,gid=mygroup,file_mode=0664,dir_mode=0775,nounix,noserverino,credentials=xxx,vers=2.0
Now it mounts without problems.
