Why Telegram Web Won’t Load Media in Group Chats

Telegram Web is a convenient way to access your chats from any browser, but sometimes media—photos, videos, voice notes, or documents—fails to load in group conversations. Below are the most common causes and step-by-step solutions to restore full functionality.

1. Browser Cache or Cookies Corruption

Old or corrupted cache can prevent Telegram Web from fetching new media files.

  1. Open your browser’s settings and navigate to Privacy & Security → Clear browsing data.
  2. Select Cached images and files (and optionally Cookies and other site data), then clear.
  3. Reload Telegram Web (CTRL+R or CMD+R).
2. Ad-Blockers or Privacy Extensions

Some ad-blockers or privacy plugins mistakenly block Telegram’s CDN domains.

  • Temporarily disable extensions like uBlock Origin, Privacy Badger, or similar.
  • Whitelist web.telegram.org and any *.cdn.telegram.org domains.
  • Refresh the page and check media loading.
3. Mixed Content & HTTPS Issues

If your browser blocks mixed HTTP/HTTPS content, media served over non-HTTPS might be blocked.

  1. Click the lock icon in the address bar while on Telegram Web.
  2. Ensure “Insecure content” is allowed (or enable mixed content temporarily).
  3. Reload and test media playback.
Note: Enabling mixed content reduces security—re-disable after testing if unnecessary.
4. Network or Firewall Restrictions

Certain networks (corporate, campus, or public Wi-Fi) may block Telegram’s media servers.

  • Try switching to a different network (mobile hotspot or home Wi-Fi).
  • Use a trusted VPN to bypass restrictive firewalls.
  • Check if your router’s DNS settings are blocking CDN domains—switch to Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1).
5. Service Worker or Offline Mode Conflicts

Telegram Web uses service workers for offline caching. Corrupted service workers might prevent media fetching.

  1. Open your browser’s dev tools (F12).
  2. Go to the Application tab → Service Workers.
  3. Click Unregister for any Telegram entries.
  4. Hard refresh the page (CTRL+F5 or Shift+Reload).
6. Telegram Web Outage or CDN Issues

Occasionally, Telegram’s CDN or web servers experience downtime.

7. Browser Compatibility Problems

Some outdated or niche browsers may not fully support Telegram Web’s features.

  • Use a modern, updated browser: Chrome, Firefox, Edge, or Safari latest versions.
  • Avoid lesser-known browsers or older versions that may lack required APIs.
8. Large Media Files or Slow Connections

High-resolution videos or large files can time out on slow networks.

  • Download media directly via the download button instead of inline preview.
  • Compress large videos or images before sending to improve load times.
  • Inform group members to use Telegram Desktop or Mobile for very large files.
Conclusion

By systematically clearing cache, checking extensions, and ensuring network and browser compatibility, you can resolve nearly all media-loading issues on Telegram Web. If problems persist after these steps, switch to the desktop or mobile app temporarily while Telegram’s web infrastructure stabilizes.
