i am trying to upgrade to proxmox 8.

after finish updating all nodes to 7.4-16, (and rebooted each node after install)
and updating ceph from Pacific to Quincy

after the update this issue occurred

chrony is setup and running on all nodes across the cluster,
reboot did not help,
delete and create monitors did not help

Whats the error? Are you 100% sure you can reach the timeserver (sometimes it is blocked, when default external ones are used). What does
chronyc sources say? Can you use chronyc makestep on each node so time-sync gets forced?
for unknown reason it resolved by itself, no issues for few hours..
( i did not do anything ) , closing thread
