  • Error message: "Gateway Anti-Virus Alert"
  • Summary: Player update server access blocked by false positive from network firewall

Symptoms​

When attempting to play a video or update the player version on shared network environments such as companies, schools, or public institutions, an error message is displayed and the process is interrupted. This typically occurs during an attempt to update Kollus Player to the latest version.

Causes​

  • Network firewall blocking: Occurs when the network firewall at the current location misidentifies the player update file as a potential threat and blocks communication.
  • External server access restriction: Occurs when file downloads from external servers not permitted by security policy (Kollus Update Server) are restricted.

Solutions​

  • Contact network administrator: Request that the network administrator of your organization allow access to Kollus Player.
  • Use mobile hotspot (temporary measure): If the security policy cannot be changed immediately, connect to a mobile hotspot and update Kollus Player.
  • Manually copy installation files (temporary measure): Download the latest Kollus Player installation file on a PC in a different environment without network restrictions, then transfer it to the current PC using a removable drive (such as a USB drive).
