Tailscale remote access works on some devices but not others
A user set up Tailscale to reach their Jellyfin media server from outside home, but some devices can connect while others cannot. This is a common setup issue usually caused by Tailscale not being logged in or configured the same way on every device.
Tailscale is a tool that creates a private, secure tunnel over the internet so you can reach your home server from anywhere. This user got it working on at least one device, but certain other devices fail to connect to their Jellyfin server — a personal media server you run yourself to stream movies and music.
The most frequent causes are: the Tailscale app on the problem device is not signed into the same account, the device is not part of the same Tailscale network (called a tailnet), or another VPN app on the device is interfering. If you run a Mac mini as a home server, the first things to check are whether Tailscale is always running on the Mac mini and whether the failing device is logged into Tailscale with the same account and shows up in your tailnet device list.
Key points
- Make sure Tailscale is running and logged into the same account on every device you want to connect from
- All devices must appear in the same tailnet — check the Tailscale admin panel to confirm
- Disable any other VPN apps on the problem device before testing, as they can block Tailscale
- Connect to Jellyfin using the Tailscale IP address (like 100.x.x.x), not the home network IP
- Updating the Tailscale app to the latest version often fixes connection issues
