3 Led strips to one power supply using esp32 & Fastled

Hi guys, new user here,
Have connected 3 led strips (each 60 leds) thru esp32 powered by one Power supply.
Cannot get first strip to light up. Checked pins, 2, 3 & 5, checked connections, switched connections to strips still that one connected to first strip won’t light up. Checked wled segments, have 0, 1 & 2 segments each with 60 length. First 0-60, second 60-120, than 120-180. Cannot see what the problem is. Anyone have any ideas? Software, config, segments???
Cheers, Ben
