  • Error code: -8028
  • Summary: Network communication disconnection and firewall blocking

Symptoms​

The video does not play and the message "The server connection failed due to an unstable network condition." is displayed.

Cause​

Interference from security programs (Virus Chaser, Bitdefender, etc.), firewall blocking of external IP ranges (not registered in the whitelist), and DNS configuration mismatch when accessing from overseas are the causes.

Solutions​

  • Check security program settings: Refer to the Conflicts with antivirus programs document to stop real-time protection in your antivirus program. After changing the settings, be sure to reboot the system to apply the changes.
  • Clear cache data (Windows): Delete the Kollus Player cache and try again.
  • Switch network environment: If the Wi-Fi signal is weak, move closer to the router or connect via a mobile hotspot to test for network loss.
  • Contact your network administrator: If the error occurs only in a specific location, ask your network administrator to allow the Kollus service ip/ports. (You can obtain the information through the customer support of the site you are using.)
  • Change DNS settings (overseas users): Change the DNS setting from your ISP's default DNS to Google Public DNS (8.8.8.8) and try again.
