  • Error code: -1002
  • Summary: Screen sharing/capture/recording program detection and conflict

Symptoms​

  • The symptom may persist even when using a different browser, and may also occur during mobile mirroring.

Causes​

  • Remote control and capture programs: Occurs when apps with capture functionality such as Chrome Remote Desktop, Steam, PicPick, or AhnCamCorder are running.
  • Browser extensions: Occurs when script manipulation plugins (such as Tampermonkey) conflict with the security module.
  • Residual processes: Occurs when related processes remain in the system tray or background even after the program window has been closed.

Browser extensions​

�phrase0�s​

The real-time protection feature of an antivirus program may falsely identify Kollus Player's security module as a threat and block it from running. Refer to the document below to temporarily disable real-time protection and then try launching the player again.

Mobile environment​

Mirroring or casting your smartphone screen to a TV or external monitor is blocked under the security policy as it is considered recording/duplication. Always watch content on the device's own screen only.
