Issue Details

I have created a WebVI by using G Web Development Software Web Module and hosted it on my computer using the NI Web Server. I can view the web application in the browser, but I cannot access the web application from my smartphone or from another computer. What might be causing this issue?

Solution

This issue is typically caused by the network configuration. When a web application is hosted using the NI Web Server, it is hosted locally on the computer running the server. To access the web application from another device, two conditions must be met:

  1. The device must use the correct link
  2. The device must be on the same local network as the computer hosting the NI Web Server.

If the devices are not on the same local network, they will not be able to reach the locally hosted application. In this situation, port forwarding must be configured on your network so that external devices can access the application.
