Slow startup DietPi

Hello everyone,

I notice after an update of dietpi and then a reboot that it safely takes 5 minutes before he’s back. I think it will come through systemd-timesyncd.service. I use pihole and bind9 (named) with my own DNS server on the PI. Could it be that the process for the time sync starting for starting pihole and bind9 (named)? and he keeps trying several times for sync the time? but that fails because the DNS doesn’t work?

Can this be solved? As I said, I’m not sure if this is the problem, but I guess so.
