  • Error code: -8403
  • Summary: Server access permission error and network blocking

Symptoms​

Video loading is interrupted or playback is rejected due to server access permission issues.

Cause​

This occurs when a network firewall identifies Kollus Player's server connection as a security threat and blocks it, or when the device has insufficient resources.

Resolution​

  • Switch network environment: Turn off the current Wi-Fi and connect to a mobile hotspot or a different network to check if playback works.
  • Reboot the device: Reboot the device to reset system resources.
  • Contact the network administrator: If the error only occurs in a specific location, ask the administrator to allow the IP/port required for Kollus service. (You can obtain this information through the customer support of the site you are using.)
