Frequently asked questions about Dashboards and Low-Code Apps

What should I do if I get WebSocket errors when using Dashboards or Low-Code Apps?

When the DataMiner web applications are not able to use WebSocket communication, this will result in WebSocket errors in the browser console.

To resolve these:

  • Make sure the WebSocket Protocol is installed and enabled in IIS. See learn.microsoft.com.

  • Open the file C:\Skyline DataMiner\Webpages\API\web.config, and make sure the targetFramework attribute of the httpRuntime tag is set to 4.5 or higher. For example:

    <httpRuntime executionTimeout="300" maxRequestLength="51200" targetFramework="4.6.2" />

  • Verify that no firewall or proxy is interfering with the setup of the WebSocket connection.

  • Use a modern browser that supports WebSockets. The DataMiner web apps do not support Internet Explorer.

What should I do if I do not see my protocol changes applied in a GQI query result?

If you have made protocol changes, but you do not see them reflected in your GQI query results, this is likely caused by GQI caching certain protocols for faster performance.

To resolve this:

  1. Launch your system's Task Manager utility.

  2. Look through the list of processes for the Skyline DataMiner Helper process.

    This process is responsible for managing GQI.

  3. Select the Skyline DataMiner Helper process and select to end it.

  4. After terminating the process, refresh your dashboard or application.

    This will prompt GQI to fetch the latest protocol changes and display accurate query results.
