minidlna fails status=255/EXCEPTION

[kalpana]

Ubuntu 22.04.1 LTS (GNU/Linux 5.15.0-50-generic x86_64)

I installed minidlna a long while ago and it was working. I just tried to use it and it is not working. I checked the setup, that all looks OK, I stopped and restarted it. I checked the status, this is what I see
Code:

There is an old log /var/log/minidlna.log.1 which is 18 months old and a newer one which is empty.
What can I do to fix it?
Thanks
