Hello,

I used LibreTime with Apache2 in Reverse Proxy, and I decided to relaunch a local radio thanks to your tool.

Today I switched from Apache2 to Nginx, but I’m not quite comfortable yet.

I started the installation from scratch, following this step-by-step guide: [How to install LibreTime 3.0.2 on Debian 11 | LibreTime](https://libretime.org/blog/2023/04/21/install-libretime-3.0.2-on-debian-11/)

An error occurs in the logs when I want to access the web interface 🙂

Nginx logs :

```auto

```

And I have a 404 error on webpage.

The server runs on Debian 11, with Nginx and PHP-FPM 7.4 (is LibreTime compatible with PHP 8.2?) and a Let’s Encrypt certificate.

Here is my Nginx config:

```auto
server {
  listen 80;
  listen [::]:80;

  server_name radio.oizos.net;

  access_log /var/log/nginx/libretime.access.log;
  error_log /var/log/nginx/libretime.error.log;

  root /usr/share/libretime/legacy/public;

  index index.php index.html index.htm;

  client_max_body_size 512M;
  client_body_timeout 300s;

  location ~ \.php$ {
    fastcgi_buffers 64 4K;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;

    # try_files $uri =404;
    try_files $fastcgi_script_name =404;

    include fastcgi_params;

    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    set $path_info $fastcgi_path_info;
    fastcgi_param PATH_INFO $path_info;
    include fastcgi_params;

    fastcgi_index index.php;
    fastcgi_pass unix:/run/libretime-legacy.sock;
  }

  location / {
    try_files $uri $uri/ /index.php$is_args$args;
  }

  location ~ ^/api/(v2|browser) {
    include proxy_params;
    proxy_redirect off;
    proxy_pass http://unix:/run/libretime-api.sock;
  }
}

```

Everything goes well on installation, except libretime-celery which seems to be missing…

```auto
systemctl --all --plain | grep libretime
libretime-analyzer.service loaded active running LibreTime Media Analyzer Service
libretime-api.service loaded active running LibreTime API Service
libretime-celery.service not-found inactive dead libretime-celery.service
libretime-liquidsoap.service loaded active running LibreTime Liquidsoap Service
libretime-playout.service loaded active running LibreTime Playout Service
libretime-worker.service loaded active running LibreTime Worker Service
libretime-api.socket loaded active running LibreTime API Socket
libretime.target loaded active active LibreTime Services

```

Did I miss something?  
Thanks for your help !

The `libretime-celery.service` has been renamed to `libretime-worker.service`.

No LibreTime is only working with PHP 7.4.

Weird, seems like the php7.4-yaml extensions is missing. The installer should have installed it.

Make sure it is installed, and it is enabled.

Conflicting oerdnj/deb.sury.org repositories! I followed this guide to get rid of it: [How to downgrade to stock packages · oerdnj/deb.sury.org Wiki · GitHub](https://github.com/oerdnj/deb.sury.org/wiki/How-to-downgrade-to-stock-packages)

Everything works now, thank you!
