minidlna not starting

[Dukeny]

Hi,

i am unable to get my minidlna to start properly on my Pi 4.

minidlna.conf has pi set as user and points to mounted drives

running systemctl status minidlna gives:
$this->bbcode_second_pass_code('', '

pi@raspberrypi:~ $ systemctl status minidlna

')

The log shows this at every start:

$this->bbcode_second_pass_code('', '[2021/10/28 14:13:34] minidlna.c:1014: fatal: Failed to switch to uid '1000'. [Operation not permitted] EXITING.')

Thank you!
