TiviMate is widely considered the premier IPTV client for Android TV and Firestick devices. However, when an error code flashes on your screen, it can leave you puzzled. Below is a comprehensive diagnostic guide for resolving every common TiviMate error message. 1. Error Code 401: Unauthorized - What it means: Your username or password was entered incorrectly, your subscription period has concluded, or your provider server is refusing the login handshake. - Instant Fix: Go to Settings > Playlists > [Your Playlist] > Xtream Codes parameters. Check that your server URL includes http:// or https:// correctly. Verify that your username and password contain no accidental trailing spaces. On Obsidian IPTV, your active line credentials are confirmed instantly via our automated provisioning dashboard. 2. Error Code 403: Forbidden - What it means: You have exceeded your active connection limit (e.g. streaming on 2 devices simultaneously on a 1-screen plan), or your ISP has blocked the specific server IP. - Instant Fix: Ensure only 1 TV is streaming at a time, or upgrade to an Obsidian Multi-Screen plan (2nd & 3rd connections discounted by 50%). If your connection limit is clear, change your DNS in your Firestick settings to Cloudflare (1.1.1.1) or Google (8.8.8.8). 3. Error Code 404: Not Found - What it means: The specific channel feed or VOD media file has been relocated or temporarily taken offline for maintenance. - Instant Fix: Go to Settings > Playlists > Update Playlist to sync your channel list with our latest cloud master index. 4. DataSourceException / HttpDataSource$HttpDataSourceException - What it means: The video player engine cannot establish a stable socket connection with the remote streaming gateway due to local network latency or timeout. - Instant Fix: Switch the internal player in TiviMate from ExoPlayer to an external player (such as VLC), or increase your Stream Format to HLS (m3u8) instead of MPEG-TS. Summary: Keeping your playlist updated and ensuring your connection limits match your subscription tier resolves virtually all TiviMate playback exceptions.
