Connection Issues on Windows

If you are having trouble connecting to your Lightform device and are using Windows, please see below for troubleshooting tips.

NOTE: If you are on a corporate network, you may need to contact your IT department in order to allow your Lightform device to connect to your company's network. In most cases, you will need to provide your Lightform device's MAC address to your network administrator. In order to obtain this, please reach out to our support team via live chat or submit a request directly from the contact us page on this guide.

Issue:

When connecting your device to your network via Ethernet, you cannot see your device in Lightform Creator's device list. Or, when trying to pair your device to a Wi-Fi network, you cannot advance past the "Connect to Lightform Device" pairing page.

Solution:

Most of the time, this issue indicates that a firewall, antivirus, or other programs on your computer are blocking the connection to your device.

First, you should verify that your firewall is set to allow Lightform Creator.

  1. Go to the Windows Start Menu and search for "Firewall" -- Choose the "Firewall & network protection" menu item.start-menu-firewall.png
  2. Select "Allow an app through the firewall"firewall-quick-settings.png
  3. Search this list for "lightform.exe". If you don't see it, choose "Allow Another App" and add "C:\Program Files\Lightform\Lightform Creator\Lightform.exe". If you do see "lightform.exe" in the list, verify that all three checkboxes are checked ("Allowed" on left, and "Private/Public" on right). You will need to click "Change Settings" in the upper right to make changes to this list. When finished, the Lightform line should look like this:firewall-lf-allowed.png
  4. At this point, you should be able to see your device in Lightform Creator. If you do not, keep reading.

Advanced firewall rules:

If the above does not fix the issue, you may have another firewall rule blocking Lightform Creator.

  1. From the "Firewall & network protection" page, select "Advanced Settings".firewall-advanced-settings.png
  2. Halfway down this window, click "Windows Defender Firewall Properties". Ensure that both the Private Profile and Public Profile are set to the following settings: 4.png    3.png
  3. Then, click "New rule" in the upper righthand corner of the Advanced Settings window, and follow these steps to allow Lightform:5.png

  6. If you still cannot see the Lightform device after this, it is possible that an existing firewall rule is blocking the connection, or antivirus/router settings (see below for more details). 

Additional troubleshooting steps:

If you still cannot connect to the device, antivirus or other software may be blocking the connection. Refer to your specific antivirus software guide for allowing other programs through (for example, this describes what to do for Malwarebytes).

If none of the above works, it is recommended to try using Lightform Creator on a second computer in order to further narrow down the issue. If the second computer allows you to connect to your device, then this indicates that there is still a program/setting that is blocking the connection to your device on the computer you tried first. Otherwise, please reach out to our support team via live chat or submit a request directly from the contact us page on this guide.

If you are having this issue only when using your device on a certain network, there is also a chance that your router has been configured to block network traffic that the Lightform device needs to communicate with your computer. Lightform Creator uses the following ports:

  • TCP 7340-7349, 50051
  • UDP 7350-7351

Refer to your router instructions for allowing traffic through these ports.
