Fortiextender show disconnected on LAN Edge Dashboard

[fireon]

Hello all, I'am using here an Fortigate 60E with some AP's an one fresh Fortiexender 201E. With strange OS Version "FXT201E-v4.2.5-build519". Strange because the fortigate is on 7.4.x. The Status is, everything is working fine, but under the Fortigate Dashboard the Fortiexender is marked es "Disconnected". What does this mean? Because it is connected. 

Please have a look at my screenshots. 

Thanks a lot

Best Regards :)

If you drill down to the FortiExtender under Security Fabric > Fabric Connectors, what does that show?

Hello Johnathan,

Strange, this day i was the first time green. I really don't know why. I've only deleted some IPSEC VPN to another Fortigate. I can't imagine how this could be related to that.
