A route page "dies" upon reloading, showing a 404 on the Server side.

[TrejoCode]

Hi, I have this test site:
https://next.trejocode.me/
And I have a route /comentarios
If you try to enter directly from the URL to:
https://next.trejocode.me/comentarios It will display an Error 404 page.

But if you access: https://next.trejocode.me/
And since you access the Link "comentarios" works.

My server is Nginx with PM2 and Reverse Proxy

Config:

    # --- Next.js (next.trejocode.me) ---

    # Aplicación
    location /_next/ {
        alias /projects/Next-VS-CRA/users-next/.next/;
        expires 15d;
        access_log on;
    }

    # Favicon
    location /favicon.ico {
        alias /projects/Next-VS-CRA/users-next/public/favicon.ico;
        access_log on;
    }

    #Manifest.json
    location /manifest.json {
        alias /projects/Next-VS-CRA/users-next/public/manifest.json;
        access_log on;
    }

    # Proxy inverso
    location / {
        try_files $uri $uri/ =404;
        proxy_pass http://localhost:3001/;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
