  • Error code: -8305
  • Summary: Unable to resolve proxy host and network routing error

Symptoms​

Communication with the server is interrupted, preventing video playback.

Cause​

This error occurs when the proxy server settings configured in the browser or system are incorrect, or when the host address of the video server cannot be identified due to a DNS configuration error.

Solutions​

Disable proxy settings​

You need to disable the manually configured proxy server options on the system to attempt a direct connection.

Windows 11​

  1. Press [Windows]+[I] on your keyboard to open the Settings app.
  2. Navigate to [Network & internet] > [Proxy].
  3. Click [Manual proxy setup] > [Use a proxy server] > [Set up].
  4. Disable [Use a proxy server] and click [Save].

macOS​

  1. Click [[System Settings]] > [Network] > click the currently connected network (Wi-Fi or Ethernet) > [Details].
  2. Select [Proxies] from the list on the left.
  3. Disable all active proxy-related entries.

Change dns settings​

To prevent domain resolution errors, refer to the DNS settings document and change from your ISP's default DNS to a public DNS such as 168.126.63.1 (KT) or 8.8.8.8 (Google).

Contact your network administrator​

In environments with strict security policies, such as companies, schools, or public institutions, changes made by individuals may still be blocked. If the error occurs only in a specific location, contact your network administrator and request that the Kollus service IP/port be allowed.
