Welcome to the World of Dark Sun zine on Kbin.social. I've been an avid Dark Sun fan since the 90's & love playing & discussing it. I'm currently working with a team to create a free 3.5e Dark Sun survival sandbox "persistent world" in the Neverwinter Nights engine.
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...)
