Cannot resolve NTP server address: Unrecognized service

General Beta 6.0

Could this be the same issue as in the previous thread?

I started seeing this on Debian 12 and DietPi

Let me know of I should check out a different branch

pihole checkout ftl tweak/ntp_delay

What is the output of

pihole-FTL --config ntp

?

pihole-FTL --config ntp

ntp.ipv4.active = true
ntp.ipv4.address =
ntp.ipv6.active = true
ntp.ipv6.address =
ntp.sync.server = pool.ntp.org
ntp.sync.interval = 3600
ntp.sync.count = 8
ntp.rtc.set = true
ntp.rtc.device =
ntp.rtc.utc = true

This time I see a different error

Unchecking these doesn't resolve it

Should FTL act as network time protocol (NTP) server (IPv4)? Unchecked
and
Should FTL act as network time protocol (NTP) server (IPv6)? Unchecked

The two options you disabled are for offering time for synchronization not for doing the synchronization itself.

This is a different issue altogether, I suppose you are running your Pi-hole in some container? The only other way you could have no permissions I can come up with right now is an outdated core version.

Please update to the latest development-v6 version. You will find a new option ntp.sync.active which you can easily set to false to prevent any syncing from happening.

Yes, the Debian is running inside Proxmox container
the DietPi is a Raspberry Pi

I see, I could've put 0 as the sync interval.
ok will update both
