Many clients will automatically discover servers running on the same LAN and display them on login. If you are outside the network when you connect you can type in the complete IP address or domain name in the server field with the correct port to continue to the login page. You can find the default ports below to access the web frontend.
This document aims to provide an administrator with knowledge on what ports Jellyfin binds to and what purpose they serve.
- 8096/tcp is used by default for HTTP traffic. You can change this in the dashboard.
- 8920/tcp is used by default for HTTPS traffic. You can change this in the dashboard.
- 1900/udp is used for service auto-discovery. This is not configurable.
HTTP Traffic: 8096
The web frontend can be accessed here for debugging SSL certificate issues on your local network. You can modify this setting from the Networking page in the settings.
HTTPS Traffic: 8920
This setting can also be modified from the Networking page to use a different port.
Service Discovery: 1900
Since client auto-discover would break if this option were configurable, you cannot change this in the settings at this time. DLNA also uses this port and is required to be in the local subnet.
Client Discovery: 7359 UDP
Allows clients to discover Jellyfin on the local network. A broadcast message to this port with
Who is JellyfinServer? will get a JSON response that includes the server address, ID, and name.
Live TV devices will often use a random UDP port for HDHomeRun devices. The server will select an unused port on startup to connect to these tuner devices.
Running Jellyfin Behind a Reverse Proxy
It's possible to run Jellyfin behind another server acting as a reverse proxy. With a reverse proxy setup, this server handles all network traffic and proxies it back to Jellyfin. This provides the benefits of using DNS names and not having to remember port numbers, as well as easier integration and management of SSL certificates.
In order for a reverse proxy to have the maximum benefit, you should have a publically routable IP address and a domain with DNS set up correctly. These examples assume you want to run Jellyfin under a sub-domain (ie: jellyfin.example.com), but are easily adapted for the root domain if desired.
While not a reverse proxy, Let's Encrypt can be used independently or with a Reverse Proxy to provide SSL certificates.
When following this guide, be sure to replace the following variables with your information.
DOMAIN_NAME: Your public domain name to access Jellyfin on (e.g. jellyfin.example.com)
example.com: The domain name Jellyfin services will run under (e.g. example.com)
SERVER_IP_ADDRESS: The IP address of your Jellyfin server (if the reverse proxy is on the same server use 127.0.0.1)
In addition, the examples are configured for use with Let's Encrypt certificates. If you have a certificate from another source, change the SSL configuration from
/etc/letsencrypt/DOMAIN_NAME/ to the location of your certificate and key.
Ports 80 and 443 (pointing to the proxy server) need to be opened on your router and firewall.
Running Jellyfin with a path (https://example.com/jellyfin) is supported by the Android and web clients.
Base URL is known to break HDHomeRun, DLNA, Sonarr, Radarr, Chromecast, and MrMC.
The Base URL setting in the Networking page is an advanced setting used to specify the URL prefix that your Jellyfin instance can be accessed at. In effect, it adds this URL fragment to the start of any URL path. For instance, if you have a Jellyfin server at
http://myserver and access its main page
http://myserver/web/index.html, setting a Base URL of
/jellyfin will alter this main page to
http://myserver/jellyfin/web/index.html. This can be useful if administrators want to access multiple Jellyfin instances under a single domain name, or if the Jellyfin instance lives only at a subpath to another domain with other services listening on
The entered value on the configuration page will be normalized to include a leading
/ if this is missing.
This setting requires a server restart to change, in order to avoid invalidating existing paths until the administrator is ready.
There are three main caveats to this setting.
When setting a new Base URL (i.e. from
/baseurl) or changing a Base URL (i.e. from
/newbaseurl), the Jellyfin web server will automatically handle redirects to avoid displaying users invalid pages. For instance, accessing a server with a Base URL of
/path will automatically append the
/jellyfinBase URL. However, entirely removing a Base URL (i.e. from
/, an empty value in the configuration) will not - all URLs with the old Base URL path will become invalid and throw 404 errors. This should be kept in mind when removing an existing Base URL.
Client applications generally, for now, do not handle the Base URL redirects implicitly. Therefore, for instance in the Android app, the
Hostsetting must include the BaseURL as well (e.g.
http://myserver:8096/baseurl), or the connection will fail.
Any reverse proxy configurations must be updated to handle a new Base URL. Generally, passing
/back to the Jellyfin instance will work fine in all cases and the paths will be normalized, and this is the standard configuration in our examples. Keep this in mind however when doing more advanced routing.
It's strongly recommend that you check your SSL strength and server security at SSLLabs if you are exposing these services to the internet.
