Fologram for HoloLens connection troubleshooting

If you’re having trouble connecting Fologram on your mixed reality device to Fologram for Rhino, we need to first establish whether it’s a network connectivity issue or a permissions issue. Any or all of the following steps may be applicable - so it’s worth testing after each step.

  1. Ensure that your device and your laptop are on the same wifi network.
  2. Install .NET Framework 4.7 or above (download) and restart
  3. Verify whether you are able to access your HoloLens via Device Portal (below).

For HoloLens: Accessing device portal

To verify whether you’re experiencing a network issue or an issue with a specific application, please attempt to connect to device portal. If you haven’t set this up this up, please see Configuring Device Portal

  1. Connect your HoloLens to Wi-Fi.
  2. Look up your device’s IP address.
  • Find the IP address on the device under Settings > Network & Internet > Wi-Fi > Advanced Options .
  1. From a web browser on your PC, go to https://<YOUR_HOLOLENS_IP_ADDRESS>
  • If you are asked for log in credentials, you have accessed the device portal.
  • If you receive a notice about a security certificate, you have accessed the device portal.

I’m able access my HoloLens via device portal:

  1. If you can access device portal via your local network but not connect to Fologram, you’re likely being blocked by a firewall. To verify this, disable your Windows firewall (and importantly any supplementary antivirus software such as McAfee)
  2. Restart your HoloLens and clear all your floating application windows (tiles)
  3. Restart your PC
  4. Ensure that your HoloLens and PC are on the same WiFi network
  5. Launch the Fologram app and attempt to connect

If this solves your issue, you can add a singular exception for Rhino (requires administrator permissions)

  1. Go to: Control Panel\System and Security\Windows Defender Firewall\Allowed apps
  2. Scroll down to Rhino 5 and/or Rhino 6
  3. Click Change settings
  4. Remove all instances of Rhino 5 and Rhino 6 .
  5. Click OK and restart Rhino.
  6. Launch Fologram and click “Add a Device”
  7. Enable Private, Public (and if applicable, Domain) and click “Allow Access”.

If issues persist:

  1. Disable any third-party firewall software (e.g. McAfee)
  2. Disable any supplementary networks:
  3. Control Panel\Network and Internet\Network Connections
  4. Click Change Adapter Settings
  5. Disable any networks that aren’t connected to the same network as the HoloLens
  6. Restart your HoloLens and PC and try again.

If you’re unable to access the device portal, or are still experiencing issues please read on.

I’m unable to access my HoloLens via device portal:

  1. Test your connection using a personal hotspot or offline router (below). Verify that you are able to access device portal. If you are still not able to access device portal, please contact Microsoft support.
  2. If you’re unable to connect your HoloLens to your PC with a portable hotspot and connect to your HoloLens via device portal please contact
  3. For enterprise and university networks, see below.

Connecting with a personal hotspot

  1. Fologram works on personal hotspots. This is a convenient way to create ad-hoc networks in locations without needing to connect to a secured WiFi network.
  2. Create a hotspot on your mobile device. You may optionally set a password for the network.
  3. Connect your PC and your HoloLens to the network.

Note: You may wish to disable mobile data whilst using the hotspot, or mark it as a metered connection in Windows to stop background synchronization tasks.

Connecting with an offline router

  1. Fologram does not require a continuous internet connection. You can set up a wireless router without internet, connect your PC and your HoloLens, and get started right away.

Enterprise Networks (including Universities)

On enterprise networks, your HoloLens and your PC must be on the same local DNS subnet. If this is a personal PC, and you logged in or were automatically logged in with your own credentials, ensuring that your HoloLens is also logged in with your credentials may resolve this issue.

To verify the DNS suffix on your computer:

  1. Go to Start\Run (Windows+R) and type “cmd”. Press OK
  2. In command prompt, type “ipconfig” and press enter"
  3. Find the “Connection-specific DNS Suffix” of your current network and note the value

To verify the DNS suffix of your HoloLens:

  1. Go to Settings\Network and Internet\Advanced
  2. Compare the DNS suffix to that of your computer
  3. If the suffix does not match, please contact your IT administrator - they will need to set up gateway routing.

If issues persist, please disable your firewall and try again.
