Why does my time synchronization always fail

[tianhua.liu]

I am the SYSTEMd timesyncd of the system. The failure of time synchronization is time out

hi,

your configured NTP server 10.4.128.211 isn't responding back, that's why it fails. you can edit your configuration in /etc/systemd/timesyncd.conf, it might also be located in /etc/systemd/timesync.conf.d/ directory.

by the way with PVE 7 we don't use systemd-timesyncd by default anymore, instead we use chrony.
