Problems with Inertia React SSR on Coolify

Hi guys,

First time posting so sorry if I'm posting in the wrong channel.

As the title says, I am running Laravel 11 + Inertia (React) on coolify. I've been able to deploy the app successfully, but the server keeps restarting. With an SPA, it works but SSR fails and I don't know what the problem is.

Navigating to the page shows a 404 after deployment. I'd appreciate any help right now as I've been on this for a while. Here's my nixpacks.toml for context:

[phases.setup]
nixPkgs = ["nginx", "python311Packages.supervisor", "..."]

[phases.build]
cmds = [
    "mkdir -p /etc/supervisor/conf.d/",
    "mkdir -p /etc/nginx/",         
    "cp $(dirname $(dirname $(command -v nginx)))/conf/mime.types /etc/nginx/",
    "cp /assets/fastcgi_params /etc/nginx/",                     
    "cp /assets/worker-*.conf /etc/supervisor/conf.d/",
    "cp /assets/supervisord.conf /etc/supervisord.conf",
    "cp /assets/nginx.template.conf /etc/nginx/nginx.conf",
    "chmod +x /assets/extra.sh",
    "ln -s /app/storage/app/public /app/public/storage",
    "...",
    "/assets/extra.sh"
]
