Control of LED beyond 2369 not possible

Hello,
I created a Light strip with 2390 LEDs and some controller. All controller are connected via DDP RGB to one “Master”-Controller.


From 0 to 2369 I can controll all LEDs via this working CURL:

curl.exe http://192.168.60.100/json -d {\"seg\":{\"i\":[2369,\"FFFFFF\"]}} -H "Content-Type: application/json"

But this code does not work with all leds beyond 2369, for example no LED on with this code:

curl.exe http://192.168.60.100/json -d {\"seg\":{\"i\":[2370,\"FFFFFF\"]}} -H "Content-Type: application/json"

Does anyone have an idea why?

Edit:
WLED v0.14.4
I can controll the LEDs If I controll them via 192.168.60.111

json has a size limit. does that curl fill an array?

omg… since 2 Weeks I was looking for this error. Now I saw, that one saved preset (loaded at boot) had the settings with one segment until 2370 LEDs. I changed it and now it works.
