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

It’s good practice to spread out “big”/"important " requests like this over a period of time on most websites so you don’t risk getting IP banned

• “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…)
