Server actions suddenly throwing 404s and I can't seem to fix it. Works locally, code rollback and DB rollback have no effect.

[noahstreller]

Summary

I have a NextJS 14.2.3 web app, but for some reason, server actions do not get called if I'm on the root page. They seem to work on other pages. I have no idea why it happens, I have tried to redeploy on a clean project, rollback the database, rollback the code, nothing works. The server logs don't show any errors either.

Please ignore my horrible commit history from the last few days, I just can't find any way to solve my issue: https://github.com/noahstreller/notenrechner-next

This is what I see in the DevTools:

Example

No response

Steps to Reproduce

Honestly no idea, i'd love to know myself. Clone the repo and deploy to vercel, I guess?
