# Fix device connection issues ### Device not showing up after installing the app After installing Buzzblender on your TV, the device should appear in your Admin Panel once you enter the access code. If it doesn't: 1. **Check that the app is open on your TV** — The app must be running to display the access code. Open the Buzzblender app on your TV and verify you see an access code on the screen. 2. **Confirm you're using the correct Admin Panel URL** — Go to [app.buzzblender.com/device](https://app.buzzblender.com/device) to enter your access code. This is the device connection section of your Admin Panel. 3. **Enter the code exactly as shown** — Access codes are case-sensitive. Type or copy the code exactly as it appears on your TV screen. 4. **Wait a few seconds after entering** — The connection can take 5–10 seconds to complete. Don't close the app on your TV while waiting. ### Access code not working If the access code on your TV screen isn't accepted in the Admin Panel: 1. **Refresh the access code** — On some devices, the access code updates periodically. Close and reopen the Buzzblender app on your TV to generate a new code. 2. **Check for typos** — Access codes contain letters and numbers. Make sure you're not confusing similar characters (like 0 and O, or 1 and I). 3. **Verify your account is active** — Sign in to your Admin Panel at [app.buzzblender.com](https://app.buzzblender.com/) and confirm your account is in good standing. If your trial expired or subscription lapsed, you won't be able to connect new devices. 4. **Try a different browser or device** — Enter the access code from a different browser or computer to rule out local browser issues. ### Connection timeout or device goes offline If your device connects briefly but then disconnects or shows as offline: 1. **Check your TV's internet connection** — Your TV needs a stable internet connection to stay linked to the Admin Panel. Test that other apps on your TV can access the internet. 2. **Restart your TV** — Power off your TV completely, wait 10 seconds, then turn it back on. Open the Buzzblender app again. 3. **Update the app** — Outdated app versions may have connection bugs. Check your TV's app store for updates to Buzzblender. ### Network or firewall issues Corporate networks, restrictive firewalls, or guest Wi-Fi networks may block Buzzblender's connection: 1. **Test on a different network** — If possible, try connecting your TV to a mobile hotspot or home network. If the device connects successfully on a different network, the issue is with your original network configuration. 2. **Check required ports and domains** — Buzzblender requires access to `app.buzzblender.com` and `play.buzzblender.com`. If you manage your own firewall, ensure these domains are whitelisted. 3. **Disable/Activate VPN or proxy on your TV** — If your network routes traffic through a VPN or proxy, it may block the connection. Try bypassing these if possible. 4. **Contact your IT department** — On business or hotel networks, IT may need to whitelist Buzzblender traffic. Provide them with the domains above. ### Platform-specific issues #### LG WebOS * Download the app from the [LG Content Store](https://ae.lgappstv.com/main/tvapp/detail?appId=1270978). * If the app doesn't appear in the store, your TV model may not support it. Check that your LG TV runs WebOS 3.0 or newer. * If the app crashes or won't open, uninstall and reinstall from the LG Content Store. #### Samsung Tizen * Samsung TV installation requires support assistance. Contact to get the latest version and installation help. * Make sure your Samsung TV runs Tizen OS (most Samsung Smart TVs from 2015 onward). #### Android TV * Download from the [Google Play Store](https://play.google.com/store/apps/details?id=com.buzzblender.tv) or use the [latest APK](https://app.buzzblender.com/api/update/latest-apk) for sideloading. * If sideloading, ensure "Install from unknown sources" is enabled in your TV's security settings. * For Android-based devices without the Play Store, the APK is the recommended installation method. #### Browser playback * If you're using browser playback at [play.buzzblender.com](https://play.buzzblender.com/), no app installation is required. * Make sure you're using a modern browser (Chrome, Firefox, Edge, or Safari). * If the browser player doesn't load, clear your browser cache and try again. ### Connecting multiple devices If you're setting up several screens at once: 1. **Connect one device at a time** — Enter one access code, confirm the device appears in your Admin Panel, then move to the next TV. 2. **Name each device** — After connecting, rename devices in the Admin Panel so you can identify which screen is which. 3. **Use the same Admin Panel account** — All devices should be connected under the same account. Don't create separate accounts for each screen. ### Using BuzzBox for non-smart TVs If you have a non-smart TV or a TV that doesn't support Buzzblender natively, BuzzBox is a plug-and-play hardware option. Contact for more information. ### Still not working? If none of these steps resolve your issue: * Email with your account email, device model, and a description of the problem. * Include the access code displayed on your TV screen if available. * Mention which platform you're using (LG WebOS, Samsung Tizen, Android TV, or browser). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
