FC error

I'm using FC version 5.6.0.1075 to connect to Fortigate. I don't know what happened but suddenly I'm getting error about Fortigate or EMS that are not reacheable (see attachement).On all interfaces the FortiTelemetry is enabled. I tried to connect manualy to my fortigate with x.x.x.x:8013 but getting the same error. My vpn connection comes up but I can not reach any internal sources. Any ideas where to search next?
