Web-Browser
Troubleshooting - Web-Browser
The N2C5 screens are implemented as pure HTML/CCS/JavaScript application. They should run in any modern web browser, including IE8 or later. When investigating any potential fault, first check that the web-browser is correctly communicating with the server.
- Ensure that the server address resolves.
- Check the Browser Console to ensure that network requests are completing.
- Check the Browser Console to ensure that no JavaScript errors are visible.
To open the Browser Console:
- In Google Chrome (Ctrl-Shift-J)
- In Firefox (Ctrl-Shift-I)
- In Internet Explorer (F12)
Note: Internet Explorer’s Browser Console feature may be disabled by default on your machine. In this case you must first enable this option once via the Local Group Policy Editor (User Configuration > Administrative Templates > Windows Components > Internet Explorer > Toolbars). The option is named “Turn off Developer Tools”.
Client Web Browser Triage
In the Browser Console you can see the requests made from the client to the web-server, and the response that is returned. You can now consider the following:
- Is the client generating JavaScript run-time errors to the console?
- Contact N-Squared Support.
- Is the client generating requests but never receiving replies?
- Check the network routing and firewall configuration between client and server.
- Is the client generating requests that generally return, but some particular requests consistently do not reply?
- Particular requests may be timing-out.
- Look in the web-server logs for further information.
- Is the server returning HTTP errors (e.g. 404 Not Found, 500 Internal Error).
- Configuration problems, or server-side NCC connection problems may be occurring.
- Look in the web-server logs for further information.
- Is the server returning HTTP success but with JSON/XML response content which indicates a server-side error?
- Configuration problems, or server-side NCC connection problems may be occurring.
- Look in the web-server logs for further information.
