Troubleshooting & FAQ

Having trouble? Most issues fall into one of the areas below.

Connecting to your server

Zuno can’t connect to my Jellyfin/Emby server

• Double-check the server URL, including the port (for example http://192.168.1.100:8096).
• Try switching between http:// and https://, as some servers only accept one.
• Make sure your device is on the same network as the server, or that the server is reachable from outside your home if you’re away.
• If Zuno found your server on the network automatically, tap it from the list rather than typing the address.

I don’t know my password / my account uses single sign-on

If your server supports Quick Connect, use Sign In with Quick Connect and approve the code from a device that’s already signed in. This works even when your account has no password.

My Plex libraries aren’t showing

Make sure you completed the Plex sign-in and authorised Zuno. You can re-run the connection from Settings.

Playback

By default, Zuno plays the original file from your media server (no transcoding). This improves efficiency and quality but requires sufficient network bandwidth.

A video won’t play, keeps buffering, or shows a black screen

• Check your connection to the server. Buffering is usually a network or server bandwidth issue.
• Lower the streaming quality: Settings → Playback → Quality. On mobile data, enable Lower Quality on Cellular.
• Try a different audio or subtitle track, as occasionally a specific track causes trouble.

Playback quality looks lower than expected

Set Quality to Highest Quality (or Original) in Settings → Playback. Note that Original and higher qualities need enough bandwidth between your device and server.

Subtitles

Subtitles are out of sync

Open the Subtitles menu during playback and adjust the Sync Offset until they line up with the audio.

The subtitles I want aren’t in the file

You can either download external subtitles and Zuno will identify them and offer as an option in the subtitle menu, or you can use Search Online… from the Subtitles menu to find and load additional subtitle tracks.

Subtitles are too small / hard to read

Customise size, colour, and style in Settings → Playback → Subtitles → Appearance.

Audio

No sound, or the wrong language is playing

Open the Audio Track menu during playback and pick the correct track. To have Zuno choose automatically in future, set your preferred languages in Settings → Playback → Audio.

Skip Intro isn’t appearing

Make sure the feature is enabled in Settings → Playback → Intros & Credits.

You are more likely to get the option to skip an intro if you have marker generation enbaled/provided by Plex Pass or the relevant Jellyfin plugin.

Trailers

Why don’t trailers play automatically on my Jellyfin/Emby server?

Plex provides playable trailers automatically. Jellyfin and Emby generally only offer YouTube links, which open in YouTube rather than playing inside Zuno. To get auto-playing trailers on those servers, add a local trailer file to the title. See Trailers for how.

Casting

Cast / AirPlay isn’t working

• Make sure your casting target is on the same network as your device.
• Confirm the device supports AirPlay or the casting method you’re using.

Account & subscription

How do I join the beta?

Open Settings → Subscription and follow the TestFlight steps. The beta requires an active Zuno Pro subscription and Sign in with Apple.

What does Zuno Pro include?

See Zuno Pro for the full list: downloads, integrations, in-app media requests, personalised recommendations, Zuno Live, Screenings, and more. Every picture and sound format plays on the free plan.

Language

Can I use Zuno in a different language from my phone?

Yes, on iPhone and iPad. Zuno is available in English, German, Spanish, French, Italian, Dutch, Brazilian Portuguese, and Swedish, and you can pick one without changing your whole device.

Open the Settings app on your device, scroll down to Zuno, and tap Language. Choose the language you want and Zuno reopens in it. To go back to matching your device, choose Automatic.

Note

The Language row only sets the language of Zuno’s own menus and text. It doesn’t change the audio or subtitle language of what you’re watching, which you still pick from the player. See Playback for those.

Still stuck?

If none of the above helps, note what you were doing when the issue happened (the title, your server type, and your device). That detail makes it much easier to get to the bottom of it and contact support.
