Mopidy not logging, TuneIn issues

How do i get mopidy to prduce a .log file? I have installed from apt, and am running as a service. The logging section of my config is:

color = true
console_format = %(levelname)-8s %(message)s
debug_format = %(levelname)-8s %(asctime)s [%(process)d:%(threadName)s] %(name)$
debug_file = mopidy.log
config_file =

I am having problems with TuneIn stations not playing. Some do, most do not, how do I set the logging to debug?

There are some problems with the tunein extension at the moment and some
kind people have worked on a fix but I’ve just not had any time to get into
it. There is a command line option to enable debug logging, I think you
need to modify the service file to set the option. But if you are debugging
something it’s often much easier to just run mopidy, with whatever command
line args you want, from the shell (as user mopidy).

OK. Thanks.

I have also tried Pi Musicbox img, and TuneIn works much better there, but not with mopidy?

Any idea what the difference is?

Musicbox uses a much older version of mopidy. A version without the changes
to playlist handling that causes this problem.
