I moved the master and slave server to new IP addresses. The slave server is a mail server. If I add a mailbox in the ispconfig interface, only the red circle is lit that the action is being performed and will never go out. Finally, the monitoring section is not up-to-date information about the slave server, there is old information before the change. But the mailbox is actually added to the slave server. Only the ispconfig interface doesn't recognize it. Log says nothing . Database connection from both sides works. Where to look for a problem?
