I would run a temporary single core wire between terminal 3 of the indoor and outdoor units to see if that solved the problem

Check that terminal 1 and 2 on indoor and outdoor are correctly wired ( not mixed)!

Re: Daikin FLXS50/RXS50
I may be your saviour.
Is the led lit on the outdoor pcb?
if not, unplug outdoor fan motor, is it now lit (blinking)
try the outdoor eev head too,
had this fault on many daikin units,
