Solex message: Check EKF Status

Goodmorning everyone

when I use Solex I get a warning message in red: “Check EKF status” while in QGC it doesn’t show me any error

Furthermore, if I want to see the event history, I do not have access to “Vehicle log” because it gives me an error “com.jcraft.jsch.jschException: Network is unreachable” (obviously the radio control is connected to UAV)

Do you have any info about it? thanks
