  • Error code: -8007
  • Related error codes: -8066, -8481
  • Summary: Network path error and IP authentication failure

Symptoms​

Video loading stops midway, or playback does not start in specific network environments (corporate network, public Wi-Fi, etc.).

Cause​

The issue is caused by incorrect DNS settings, authentication rejection due to VPN virtual network or proxy usage, or blocking of specific IP ranges and data bandwidth by network management policies.

Resolution​

  • Disable VPN: If a VPN program or virtual network service is active, make sure to terminate it and connect using a standard network.
  • Reassign IP and reset network: Obtain a new IP address.
    • Mobile: Enable airplane mode, wait 5 seconds, then disable it again to receive a new IP address from your carrier.
    • PC: Reboot your router.
  • Change DNS settings: Switch to Google Public DNS (8.8.8.8) instead of your carrier's default DNS, then try again.
  • Check security program settings: Refer to the antivirus program conflicts document and disable real-time protection in your antivirus program. After changing the settings, be sure to reboot the system to apply the changes.
  • Switch network environment: Check whether you are on a public Wi-Fi or corporate network with data download limits, and if possible, connect to a mobile hotspot to test whether playback works normally.
  • Contact network administrator: If the error only occurs in a specific location, ask your network administrator to allow Kollus service ip/ports. (You can obtain the information through the customer support of the site you are using.)
