How to diagnose a blocked stream

  1. Paste stream URL: Use a single channel URL from your M3U.
  2. Run diagnostic: Server and browser probes collect status codes.
  3. Read report: Review ISP block, geo, CDN, and token sections.
  4. Try fixes: Use VPN, different DNS, or native IPTV app as suggested.

Frequently asked questions

Is ISP Block Detector free to use?

Core use is free or included in your account tier. Some advanced actions may use credits — see the badge on the tool card for current pricing.

Do I need to install software?

No. ISP Block Detector runs in your web browser on desktop, tablet, and mobile.

Is my playlist data safe?

Many tools process locally in the browser; server-assisted tools handle files securely and do not sell your URLs or credentials.

What file formats are supported?

Standard M3U and M3U8 playlists are supported, including common IPTV attributes like group-title, tvg-logo, and tvg-id.

Will output work with TiviMate, IPTV Smarters, or Kodi?

Yes. Exported playlists follow common M3U conventions compatible with major IPTV players.

Can I use this on my phone?

Yes. The tool interface is mobile-responsive so you can upload and download from Android or iOS browsers.

Does a pass here guarantee TV app playback?

Native IPTV apps may bypass browser CORS limits; failing here but working in TiviMate is common.

Can I test a full playlist?

This tool focuses on one URL — use Stream Validator or Health Lab for bulk checks.
