Nginx

"Nginx (pronounced "engine X") is a web server which can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. The software was created by Igor Sysoev and first publicly released in 2004.[9] A company of the same name was founded in 2011 to provide support and Nginx plus paid software." - Wikipedia

Nginx from a subdomain (jellyfin.example.org)

Create the file /etc/nginx/sites-available/jellyfin which will forward requests to Jellyfin. After you've finished, you will need to symlink this file to /etc/nginx/sites-enabled and then reload nginx. This example assumes you've already acquired certifications as documented in our Let's Encrypt guide.

Note that a server listening on http port 80 is required for the Certbot / Let's Encrypt certificate renewal process.

HTTPS config example

server {
    listen 80;
    listen [::]:80;
    server_name jellyfin.example.org;

    # Uncomment to redirect HTTP to HTTPS
    return 301 https://$host$request_uri;
}

server {
    # Nginx versions prior to 1.25
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    # Nginx versions 1.25+
    #listen 443 ssl;
    #listen [::]:443 ssl;
    #http2 on;

    server_name jellyfin.example.org;

Censor sensitive information in logs

This censors any api_key URL parameter from the logfile.

#Must be in HTTP block
log_format stripsecrets '$remote_addr $host - $remote_user [$time_local] '
                    '"$secretfilter" $status $body_bytes_sent '
                    '$request_length $request_time $upstream_response_time '
                    '"$http_referer" "$http_user_agent"';

map $request $secretfilter {
    ~*^(?<prefix1>.*[\?&]api_key=)([^&]*)(?<suffix1>.*)$  "${prefix1}***$suffix1";
    default                                               $request;
}

#Must be inside server block
#Insert into all servers where you want filtering (e.g HTTP + HTTPS block)
access_log /var/log/nginx/access.log stripsecrets;

Nginx Proxy Manager

Nginx Proxy Manager provides an easy-to-use web GUI for Nginx.

Create a proxy host and point it to your Jellyfin server's IP address and http port (usually 8096)

Enable "Block Common Exploits", and "Websockets Support". Configure the access list if you intend to use them. Otherwise leave it on "publicly accessible".

In the "Advanced" tab, enter the following in "Custom Nginx Configuration". This is optional, but recommended if you intend to make Jellyfin accessible outside of your home.

    # Disable buffering when the nginx proxy gets very resource heavy upon streaming
    proxy_buffering off;

In the "SSL" tab, use the jellyfin.example.org certificate that you created with Nginx Proxy Manager and enable "Force SSL", "HTTP/2 Support", "HSTS Enabled", "HSTS Subdomains".
