Reverb does not start on production server

I have tried everything now, but I despair. But it won't run locally on the server.

I have a Linux server with plesk.

I'm having trouble knowing what to do with the ssl. I am using LetsEncrypt. Can I use that or do I have to use something else? How do I integrate it?

The whole thing is only used internally and not externally.

This is what my nginx looks like, which irritates me, in the tutorials it always says host $http_host, but in the file there is no such thing, it says host $host. Is the $http_host correct now or do I have to change it to $host?

server {
        listen server_ip_v4:443 ssl;
        listen [server_ip_v6]:443 ssl;

        ssl_certificate             "/opt/psa/var/certificates/dfghuzkuiksdf"
        ssl_certificate_key         "/opt/psa/var/certificates/dfghuzkuiksdf"

        location / {
                proxy_pass http://127.0.0.1:8880;
                proxy_redirect http://$host:8880 $scheme://$host;
                proxy_set_header Host $host;

        }

        location /app {

                proxy_set_header Host $http_host;

                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "Upgrade";

                proxy_pass http://0.0.0.0:8080;
        }

        location ~ /(ws|websocket)(/|$) {
                proxy_pass http://127.0.0.1:8880;
                proxy_redirect off;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "Upgrade";
                proxy_set_header Host $host;

                access_log off;
        }

        underscores_in_headers on;
}

Then here is my env

QUEUE_CONNECTION=sync
BROADCAST_CONNECTION=reverb
REVERB_APP_ID=?_id
REVERB_APP_KEY=?_key
REVERB_APP_SECRET=?_secret
REVERB_HOST="meinwarden.de"

REVERB_SCHEME=https

VITE_REVERB_APP_KEY="${REVERB_APP_KEY}"
VITE_REVERB_HOST="${REVERB_HOST}"
VITE_REVERB_PORT="${REVERB_PORT}"
VITE_REVERB_SCHEME="${REVERB_SCHEME}"

and I call that:

php artisan reverb:start --debug
INFO  Starting server on 0.0.0.0:8080 (meinwarden.de).

Error message is then just:
