# 🛠 Troubleshooting IPTV on Smart TVs (Samsung, LG, Android TV)

***

### 📦 Installation Issues

**❌ App Not Found in the App Store (Samsung/LG)**

* The app might not be available in your region or on your TV model
* ✅ **Solution**:
  * Change your TV's region (check Settings or Smart Hub reset options)
  * Make sure your TV’s firmware is up to date

**⚠️ "Unknown Sources Blocked" (Android TV)**

* Android TVs block third-party apps by default
* ✅ **Solution**:
  * Go to **Settings → Security & Restrictions**
  * Enable **Install from Unknown Sources** for Downloader or browser

***

### 🔐 Login Problems

**❌ Invalid Credentials / Login Failed**

* Often due to incorrect server URL or account input
* ✅ **Solution**:
  * Double-check **username**, **password**, and **server URL**
  * Try using **Xtream Codes API login** instead of M3U if possible

**🚫 "User Blocked" or "Banned"**

* We may have disabled your account or IP
* ✅ **Solution**:
  * Contact us to reset or unblock your access

***

### 📺 Playback Issues

**⛔ Channels Not Loading**

* Possibly due to network errors or expired playlist
* ✅ **Solution**:
  * Restart the app
  * Check your internet connection
  * Try re-adding your user details

**⏳ Buffering or Lagging Video**

* Usually due to slow Wi-Fi or ISP throttling
* ✅ **Solution**:
  * Use Ethernet cable if possible
  * Reboot your router
  * Enable a VPN on your router if throttling is suspected

***

### 💥 App Crashing or Not Opening

**🔄 Samsung/LG:**

* Clear app data (if option exists) or delete and reinstall

**🔄 Android TV:**

* Go to **Settings → Apps → \[App Name]**
  * Tap **Clear Cache** and **Clear Data**
* Reinstall the app using **Downloader** with the correct code

***

### 🌟 Best Practices for Smooth Performance

* ✅ Keep your Smart TV firmware up to date
* ✅ Restart your TV every few days to clear memory
* ✅ Prefer **Xtream Codes** login over M3U when possible
* ✅ Use a **wired connection** for stable playback
* ✅ Don’t run too many background services on Android TV

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
