I have a Raspberry Pi 3 setup with three separate 8 channel relays for a total of 24 relays running FPP. I ran a test sequence a few days ago with about 3/4 of the lights plugged in. Everything ran great and looked good. I plugged in the rest of the lights and ran the same sequence a day later and a good portion of the lights plugged in wouldn't turn on and blink. I have tested the lights and verified that they work when plugged into a power source, but for some reason, they won't blink when the relay turns them on. All 24 relays appear to be working and clicking on and off. This is my first year, and I'm very confused as to why some of the lights aren't working. Any help would be much appreciated. Thank you!

Need more details to say the exact cause but maybe your power supply could be overloaded when you have the rest of the lights connected. Do a few checks of voltages with a multimeter if you have 1 handy.
