GCS Failsafe Triggered mode RTL after Takeoff

Hi,

Plane triggered RTL within few minutes after takeoff, found GCS Failsafe ON in messages but FS_LONG_TIMEOUT is set to 300 seconds which didn’t happen before triggering the failsafe. This is the first time I encountered something like this, not able to figure out what caused this.

Flight details:
Firmware: ArduPlane-4.3.4
Type: Quad-Plane

GCS Failsafe Parameters:
FS_GCS_ENABL,1 (ENable)
FS_SHORT_ACTN,3 (Disable)
FS_LONG_ACTN,1 (RTL)
FS_LONG_TIMEOUT,300 (5min)

Am I missing anything here. Any help is appreciated.

Please find the flight log file attached.

Thank you…!!
