Were you trying to post a link or perform witchcraft? That's the only times I've ever gotten that error. Either way, meltingwax needs to make a custom error message, like the "AHHHHH" you sometimes get when posting blocked stuff.
HTTP status ranges in a nutshell:
1xx: hold on
2xx: here you go
3xx: go away
4xx: you fucked up
5xx: I fucked up
F5
I've been having a similar problem too. Sometimes it results in double posting.
Also, meltingwax, please fix the rules.

Wrong, with 4xx like 404 error it often indicates that dickhead website admins deleted tons of content resulting in many 404 errors.
429 might also indicate that a website is being stingy with its content.
Errors I saw in Fri Aug 20 16:~06:44 2021 UTC:
** black text: "Sorry \ Please try again in ~1 min. Crawling this host is paused because they notified us that are overloaded right now."
*** still has a typo: "they notified us that [sic, the word 'they' should be here] are overloaded right now"
** red text: "Please try again in a few minutes. Crawling this host is paused because they notified us that they are overloaded. (HTTP status=429)"
*** the "they notified us that are overloaded right now" typo was fixed?
