  • Error code: 1027, 3019
  • Summary: Content tampering detection and security policy block

Symptoms​

During video playback, content tampering (manipulation) is detected and playback is forcibly terminated according to the security policy.

Cause​

This occurs when a browser extension (plugin) modifies the player's source code, or when an attempt to artificially manipulate or extract video data is detected.

Main programs detected​

  • Ad-blocking tools: Programs that interfere with the video playback script flow, such as AdGuard
  • Userscript execution tools: Plugins that arbitrarily modify the browser's default behavior, such as Tampermonkey
  • Unofficial video downloaders: Extensions that forcibly extract video streaming URLs

Resolution​

You must remove or disable browser extensions that conflict with the security policy. After changing the settings, be sure to completely close and restart the browser.
