time synchronization problem after change db

[davide.filippi]

Good day
Yesterday I've moved the db from a virtual server to a physical server with another ip address.
Dump from old virtual server and restore in the new one.
In the new db server I've run ADMIN change ip perl and in the PBXs i've set the new db ip address on /etc/astguiclient.conf.
Today, several x-lite connect to a specific PBX don't receive the vicidial call and a message "There is a time synchronization problem with your system" is appear.

What I can search for the troubleshooting?

Thanks

Go to "Reports", then click on the plus sign "+" in the top corner of the servers list at the bottom of the page. It will show you what time it thinks it is for each dialer, the webserver and the database.

Checked but time of all servers are synchronized.
This issues is apply only to 2-3 workstation. Others works well



edit
this issues seems to be generalized
