- 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
- Press [Windows]+[I] on your keyboard to open the Settings app.
- Navigate to [Network & internet] > [Proxy].
- Click [Manual proxy setup] > [Use a proxy server] > [Set up].
- Disable [Use a proxy server] and click [Save].
macOS
- Click [[System Settings]] > [Network] > click the currently connected network (Wi-Fi or Ethernet) > [Details].
- Select [Proxies] from the list on the left.
- 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.
