HTTP 429 is “Too many requests”, so you’re spamming your home instance too much & is using bot protection against you.

“big” usually meaning rarer requests, also like post creation, image upload, etc. Basically things people don’t “normally” do (as opposed to normal things, like scrolling through posts, upvoting, subscribing…)
