All electrical connections must be tight and the control needs a good ground. Check first. This is a common problem even on residential equipment.

Sounds like a partially restricted burner orifice. Poor flame across the igniter which also sensor for flame. Because you say it lights when you aim an external flame at the gas I have to believe the flame is crooked or weak it won't be sensed properly. Pull the orifice, blow it out with air or replace. DO NOT POKE IT WITH A WIRE!
If you light it with a propane torch, leave the torch lit with the flame touching the igniter to see it it will stay lit once the clicking stops. If it does it's a flame issue if it still goes out it probably in the control.
I am assuming the igniter did spark in the first place, but you didn't mention if it did. That should be the clicking you hear.
