Failed to raise ambient [CAP_CHOWN=0]

Help docker

Hello!
I run docker 2022.8 in docker Synology 6

The DNS service does not work.
In the log I see:

Starting pihole-FTL (no-daemon) as pihole stdout
failed to raise ambient [CAP_CHOWN=0] stdout
Stopping pihole-FTL stdout

In the interface I see:

Error

There was a problem applying your settings.
Debugging information:
PHP error (2): fsockopen(): unable to connect to 127.0.0.1:4711 (Connection refused) in /var/www/html/admin/scripts/pi-hole/php/FTL.php:44

Quoting the Upgrade Notes from our Docker guide, did you try setting DNSMASQ_USER to root?

  • In 2022.01 and later, the default DNSMASQ_USER has been changed to pihole, however this may cause issues on some systems such as Synology, see Issue #963 for more information. If the container won't start due to issues setting capabilities, set DNSMASQ_USER to root in your environment.
