Buffering and freezing<\/h3><p>Restart your router and device. Use a wired connection or 5 GHz Wi-Fi. Make sure you have at least 10 Mbps (HD) or 25 Mbps (4K) per screen. In TiviMate or Smarters, switch the player to a different decoder (hardware\/software) and lower the buffer size if it keeps freezing. Close other streaming apps on the same network.<\/p><h3>2. Login or authentication errors<\/h3><p>Copy the server URL, username and password exactly as sent, with no extra spaces. Check that your plan or trial is still active in your dashboard. If you see \u201cmax connections reached\u201d, another device is already using your line: close it or upgrade to more connections.<\/p><h3>3. Channels not loading<\/h3><p>Refresh the playlist in your app. If one channel fails, try its FHD or HD version. If none load, restart the app and check your internet connection. Some networks block streaming ports, so try another network or a VPN.<\/p><h3>4. TV guide (EPG) not showing<\/h3><p>In your app's settings, update or reload the EPG. Set the EPG time shift to your time zone. It can take a few minutes after first login.<\/p><p>Still empty? Try the fixes in IPTV SUBC's guide to an <a href=\"https:\/\/iptvsubc.com\/iptv-guide-empty-fixes\/\">empty or wrong IPTV guide<\/a>.<\/p><h3>5. App crashes or won't open<\/h3><p>Clear the app cache, update to the latest version or reinstall it. On Firestick, free up storage by removing unused apps.<\/p><h3>6. Poor picture quality<\/h3><p>Choose the HD or 4K version of a channel, check your speed and avoid Wi-Fi extenders where possible.<\/p><h3>7. No sound or audio out of sync<\/h3><p>Change the audio track in the player, switch the player decoder, or restart the channel.

Buffering happens when the data cannot arrive fast enough. Knowing the cause helps you fix it for good.<\/p>\n<h3>1. Internet speed and stability<\/h3>\n<p>A 4K stream needs about 25 Mbps and an HD stream about 10 Mbps. If several people stream or download at the same time, each stream gets less. Run a speed test on the device you watch on, not on your phone.<\/p>\n<h3>2. Wi-Fi interference<\/h3>\n<p>Walls, microwaves and neighbours' networks slow down 2.4 GHz Wi-Fi. Switch to 5 GHz, move the router closer or use an Ethernet cable. A Firestick Ethernet adapter costs little and fixes most buffering.<\/p>\n<h3>3. Internet provider throttling<\/h3>\n<p>Some providers slow down streaming traffic at peak times. If buffering only happens in the evening, a VPN can help.<\/p>\n<h3>4. The device and app<\/h3>\n<p>Older devices struggle with 4K. Clear the app cache, close background apps and keep your player updated. In TiviMate and IPTV Smarters you can change the video decoder in settings, which fixes freezing on some devices.<\/p>\n<h3>5. Connection limits<\/h3>\n<p>Each plan allows a set number of simultaneous streams. Watching on more devices than your plan allows causes errors.
