It is too short to complete ESC calibration in QGC

Hello ! Anybody advice me, it is too short time to complete 8 ESCs calibration:
before beep sounds of calibration ending " calibration timeout" appears on PC screen.
Is there any way to lengthen this time ?
Thanks.

Oct coax x8 drone (8escs & 8motors) seems to need more time to calibrate than quad.
