NZXT H6 Flow RGB Case Fans Aren't Lighting Up

I don't have an NZXT controller, I directly connected 3 front case fans to my 5V ARGB port on my MSI motherboard. RGB lights used to work for the first few weeks when I first built my PC but it stopped working like a month ago. Sometimes they light up, but instead of lighting in sync with my CPU fans (like I set them up on MSI Center), they light up in a solid color for a short time and then they stop lighting up completely. This happens rarely though, most of the time they never light up. Even tho MSI center detects ARGB port that they're connected into, they still do not work. What is the reason for that? And how can I fix it?

Here's a video I took when I first built my PC, you can see that the RGB lighting used to work fine.
