@molly0xfff For the less tech savvy, 404 is not an error you retry.

Pretend you're calling someone on the phone.

429 is roughly "Hey Molly, call back later, I'm waiting for another call"

500 is when you just get some weird beeps when you call the number, something broke at the other end.

302 is "Jeff changed his number, you can reach him at 555-1212"

404 is "Sorry, wrong number. No Jeff here."

Retrying a 404 is like calling back after you're told you have a wrong number, just in case there's now a Jeff there -- and in this case, doing it as soon as you hang up, over and over.
