What's the best thing to do if your account performs normally then a video suddenly doesn't go on fyp at all?

I'm new at creating content on tiktok and my account has been doing very well, ranging from 1k and above views for pretty much all of my 10 or so videos, decent engagement. Yesterday I upload a video and the views were stuck at like 1/2, and I knew only my followers were able to see it because they were the only ones who interacted with it with likes and comments. I left it alone because I thought the algorithm was making sure of its jimbo jambo or whatever, but 1 whole day later and the video is still stuck at 35 views, which I assume is all from followers or profile views. What happened, why is my video getting absolutely 0 traction for no apparent reason? What should I do next to make sure it doesnt happen again?
