Nitrous stopped working and WILL not work again

Hey guys, whenever I first got beam my nitrous worked flawlessly like it should, and did for a couple months, then all the sudden it stopped. I’m in a big community of beam drag racers and we’ve looked through what I think is all my settings and I’ve tried everything and still can’t get it to work. It shows up, you click it, it turns green and purges like it’s ready to work and then it just never activates. Any help would be appreciated. Thanks In advance
