Unbound and Logitech Media Server: Couldn't resolve IP address

[Wouter Wijngaards]

Hi Bern,

If it keeps happening, try setting verbosity 4, then unbound prints more
and more debug information what is going on.  I guess it is unable to
get replies from the network.  I don't really know what is going on either.

Best regards, Wouter
