When this error occurs, there could be many causes:
- Network Instability: High latency, packet loss, or an unstable network connection can corrupt the data stream.
- VNC Server Configuration: The VNC server may not support the encoding type requested by the client.
- Encoding/Compression Issues: Mismatch in the supported encoding methods between the server and client (e.g., Tight, H.264, or ZRLE) or a compression-related issues during data transmission.
- Corrupted Data Stream: A corrupted or incomplete data stream can occur due to hardware issues, such as faulty network equipment or memory.
- Server Overload: The VNC server might be overloaded or unable to process incoming data properly due to high demand.
Troubleshooting Steps:
- Check Network Stability: Test your network connection for latency and packet loss.
- Update Software: Ensure both the VNC server is up to date.
- Verify Configuration: Match the connection encoding settings under "Advanced" with the server’s supported methods.
- Restart: Restart both the source and destination computers to reset the session.
- Monitor Logs: Check the server logs for detailed error messages.
- Simplify Setup: Temporarily disable encryption, firewalls, or proxies to identify if they are causing the issue.
