Device[SYSLOG-0A0F3201] did not receive any log in last 53 minutes.

FG 600D -> v5.6.0 build1449 (GA)
FAZ 300D -> v5.6.0-build1524 170601 (Beta 2)
I note that the FG600D sends the logs and they are stored in the FAZ, but when they enter the FAZ FortiView they are not displayed in real time, and the message indicated in the title in the event log appears.
