How do I generate debug logs in VNC Connect?


When do I need to enable debug logging?

If you contact RealVNC's Support team, you’ll almost certainly be asked to provide debug logs. This means dialing the log level up to include much more information, recreating the problem, and then sending the new log file in so that we can help you find a solution.

How do I enable debug logging?

You can enable debug logging quickly and easily in the Options/Preferences area of VNC Viewer and VNC Server. Here's how:

VNC Server

  1. Locate the VNC Server icon. This is in the bottom right, by the clock, on Windows, or in the top right for Mac/Linux. You may need to click the little arrow to reveal additional icons if the VNC Server icon is not visible. Once you have located it, right click on it and click 'Options'.

  3. Click 'Troubleshooting', then select 'Create a debug log file'.

  3. Click 'Logging', then select 'Create a debug log file'.
  4. Click 'OK'.
  5. Restart VNC Viewer.

Where do I find the log files?

To open the folder that contains the debug log files, click the 'Show in Folder' button. This can be found in the same area where you enabled debug logging (see How do I enable debug logging?)
