ntp time sync how to disable

Hi everyone, I've been installing pihole du proxmox as LXC for years. In the latest version I can't upgrade because when restarting a denied access error to the ntp.

I wanted to know where I can find the parameters to disable the NTP sync. My version is * Pi-hole v5.18.4 .
Dall'immagine del setup non trovo la voce ntp ...

Pi-hole v5 did not offer NTP support.

Your screenshot suggests you are still running Pi-hole v5?

I m afraid to yes

Does your problem occur during the update to v6 or after the successful update and you restored a backup?

Pi-hole v6 features a simple NTP server and client. That may cause pihole-FTL to report errors, but that would only happen after upgrading to v6.

Does that mean you did upgrade to v6, but then reverted to Pi-hole v5?

With Pi-hole v6, you may disable the NTP server by running:

sudo pihole-FTL --config ntp.ipv4.active false
sudo pihole-FTL --config ntp.ipv6.active false

And to disable the NTP client:

sudo pihole-FTL --config ntp.sync.active false

Of course, you'd need Pi-hole v6 installed to run those statements.

After I'm upgrading pihile when the reboot system , the error appear and the hosts on the lan not resolving any url .
I have to restore the latest backup

So can I try to upgrade and then run the parameters you provided me?

I'have upgrade my pi-hole server to version 6 . I'have disable time server from menù and the system running very good , but i'have encored a problem from SVC query . I 'can resolve this ?
