Are you experiencing the 421 error?

421

There is a rolling "Error 421" page that is effecting MelonLand sites; I am currently unsure what its cause is or how to fix it; my research as all turn up no success 

If you encounter the error 421 page please report its whereabouts here and the circumstances that lead you to encounter it!

For any sysadmins out there: there is a help thread on this forum you can follow if you would like to offer assistance! https://community.letsencrypt.org/t/421-misdirected-request-on-nginx-hosting-multiple-subdomains/232934/1

EDIT 04/02/2025: This issue has been resolved (I think!!) - I would still like to know if anyone encounters it - for anyone encountering it on their own server; enabling http2 on all sites seems to have been the solution.
