NGINX invalid gateway 502, upstream sent too big header

Hi, I have a problem I never encountered before:

[error] 26#26: *147 upstream sent too big header while reading response header from upstream, client: 192.168.0.3, server: localhost, request: "GET /xxxxx/xxxxxxx HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxxxxxxx-xxxxxxxxxx.up.railway.app"

[error] 26#26: *147 upstream sent too big header while reading response header from upstream, client: 192.168.0.3, server: localhost, request: "GET /xxxxx/xxxxxxx HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "xxxxxxxx-xxxxxxxxxx.up.railway.app"

This is using the Nixpacks, so I dont think I can edit the nginx.conf file, if this only solvable by using docker, could someone guide me trough it, I never used docker, but my github repo of this project is open so anyone could take a look at it! Its boilerplate material right now, but I want to make a game with Vue and Laravel. https://github.com/GILLESMaster/Krilinga Project ID (e54f7042-71b3-4bc4-b530-c2d41b9cad7c) 🙏 Thx in advance!

Solution:

you actually can provide your own nginx config https://nixpacks.com/docs/providers/php...

Other pages work Altough you can get to this page, refreshing will result in 502 bad gateway with the

@Brody nginx: [emerg] host not found in "${PORT}" of the "listen" directive in /app/nginx.conf:25 this also gave me errors

include    $!{nginx}/conf/mime.types;

include    $!{nginx}/conf/mime.types;

I think the placeholders dont get updated? I fixed the mime.types by using a custom one in the root dir and pointing to that but how do I asign the random port each time?
