How to control RGBW 5pin led strip with A16 controller

[MariusM]

I have the following case:
I have KC868 server, i configured the GPIO for 5 V led strip - all working fine.
I have K868 AP , i configured for RGBW led strip 24 V - all led's working fine.

The issue is that when i turn on the both Led strips 24 V and the 5V data led strip , the 5 V data strip start to fliker when changing the colours.
Do you have any idea why KC868 AP influences the server GPIO and makes all leds frome 5 V strip to fliker ?
The fliker is more like all leds are going crazy during changing the colours.

take a photo how you wire your board.

The power supply negative - from 12V and 5V are connected together. 
On right side is the 24V power supply.

KC868-Server and KC868-AP all work with DC24V power supply?

No, the server is 12 V , kc-868-AP is at 24V

KC868-Server support DC12-24. suggest you use one DC24V power supply. not need to use DC12v power supply.

I changed to 24V server and AP , but still same symptoms. 
I also connected the negative - from 5V supply to negative - 24 V. 

It’s strange because the 5V led strip works fine only if I turn off the RGBW from KC868-AP. 
When RBGW is turned on and I want to change the colour of 5V strip led , the 5V strip act haotic on colours.
