Your server

Away from home

Reach your Jellyfin from anywhere with Tailscale, built into Mira on Windows, Mac and iPhone, without opening anything to the Internet.

  • Windows
  • Mac
  • iPhone

At home, Mira reaches Jellyfin directly. Away, it goes through Tailscale: a free private network between your own devices, encrypted end to end. Jellyfin stays closed to the rest of the Internet.

On the Jellyfin PC#

The PC that runs Jellyfin needs the real Tailscale app, signed in to your Tailscale account.

  1. Install Tailscale from tailscale.com/download and sign in. A free personal account is enough.
  2. In Mira for Windows, open the guide (F1) and click Set everything up on the Mira on your iPhone card. It opens Jellyfin to your Tailscale devices in the firewall, turns on Tailscale's Run unattended (so it works before anyone signs in to Windows), and keeps the PC awake on mains power.
  3. The card then gives the Tailscale address to type on your devices. It works at home too.

If the PC sleeps, Tailscale cannot wake it. On a laptop on mains power, set closing the lid to Do nothing.

On your other devices#

Each device can either have the Tailscale app, or use Built-in Tailscale, which is inside Mira. Built-in Tailscale makes Mira one more device on your Tailscale network, only while Mira is open. When the Tailscale app is connected on a device, Mira uses it and does not offer its own.

On Windows and Mac#

  1. On the sign-in screen, type the Jellyfin PC's Tailscale address (100.x.y.z) or its name. Mira offers Sign in to Tailscale; it also does when it finds no server.
  2. Your browser opens Tailscale's sign-in page. Sign in with the account of the Jellyfin PC.
  3. If your Tailscale network approves each new device, approve mira-<computer name> in its admin console (Open Tailscale's admin console).
  4. If the firewall asks to allow Mira's Tailscale, accept: the direct connection is faster. Refusing works too, through a Tailscale relay.
  5. Sign in to Jellyfin as usual.

Mira then joins your Tailscale network each time it opens and leaves when it closes. Settings → Account & server → Built-in Tailscale shows its state and the path Mira takes: At home (direct), Through the Tailscale app or Through Built-in Tailscale.

On iPhone and iPad#

  1. Mira → Settings → Away from home → turn on Built-in Tailscale, then Sign in to Tailscale. Not signed in to Jellyfin yet: on the sign-in screen, Away from home: Built-in Tailscale.
  2. Tailscale's page opens over Mira: sign in with the account of the Jellyfin PC. Mira closes it once the iPhone is connected. Your Tailscale password stays on Tailscale's page.
  3. If your network approves each new device, approve mira-iphone in the admin console.
  4. From the sign-in screen, Mira finds Jellyfin on your Tailscale network. Already signed in: nothing else to do. When the Wi-Fi doesn't lead to Jellyfin, Mira goes through Built-in Tailscale.

Settings → Away from home → Path to Jellyfin says which way Mira goes, and whether the Jellyfin PC is online on Tailscale. No VPN profile is needed, so it works with AltStore Classic and a free Apple ID. Through Built-in Tailscale, a video sent with AirPlay is still played by the iPhone: the TV cannot reach Jellyfin through it.

Keep it working#

  • Key expiry. A Tailscale device's sign-in expires after 180 days by default. Mira warns you two weeks before. In the admin console, ⋯ → Disable key expiry on the device avoids it, for the Jellyfin PC too.
  • Signing out. Sign out of Tailscale in Mira's settings tells Tailscale, then erases Built-in Tailscale's keys from the device. The device stays in your console, "Logged out", until you remove it there.

When Tailscale itself is down#

If Tailscale's coordination servers have an outage, devices that are already set up can keep reaching each other from the list of devices they keep. Tailscale only allows this when your network's policy says so. Mira offers it under Built-in Tailscale in its settings, with Copy the line; in your network policy, paste it just below "nodeAttrs": [ (if there is none, add the whole block after the first {):

"nodeAttrs": [
  { "target": ["autogroup:member", "autogroup:tagged"], "attr": ["cache-network-maps"] },
],

A friend without Tailscale#

To watch with someone who is not on your Tailscale network, send them your party link: it opens only Mira to the Internet, through Tailscale Funnel, never the rest of Jellyfin.
