Cannot Connect RC

I am unable to get any output from my servo rail using a remote control. Servos respond if I move the FC (via arduplane). Not sure why I am not able to use RC. The Navio2 is powered from a battery and the servo rail is powered from the BEC of an ESC.

cat /sys/kernel/rcio/status/alive returns 1

cat /sys/kernel/rcio/rcin/ch2 (or 1, 3, 4) return 0

Please help! Thanks!

edit: Using Frsky R-XSR and X9 Lite

Issue was with connection. Video below details reason:
