FortiClient EMS - Network connection error

Started getting these network connection errors every hour on EMS.  Anyone experience?  Can ping 173.243.143.6.

Same probleme here. Nothing blocked on the firewall (Fortigate -> ISDB: Microsoft-Azure, Fortinet-FortiGuiad, Fortinet-FortiCloud).

Same issues here post upgrade to 6.4.4.
 
If you are seeing this issue it is also likely causing issues with getting updated EMS deployment packages.
 
I resolved my issue by setting FortiGuard services in EMS portal to not use SSL then reran FcmUpdateDaemon.exe to trigger update and the issue was resolved.
 
Hopefully this helps.

Same here, couldn't figure out why our EMS was stuck on 6.4.3 as the "latest" and realized it wasn't assigned to our firewall policy that excludes some hosts from deep SSL inspection on the fortigate. The instant I turned this on it was resolved and loaded up 6.4.6.

Yes, port 8000 is reserved for connections into the FortiGate from EMS. Doc doesn't indicate it but I thought it was that FortiGuard uses but doc says it's also for FSSO.
