Local File Network troubleshooting

Last Updated: February 3, 2021

Note: Local File Networking supports a maximum of 10 players on a local network. Exceeding this recommended number may cause unreliable behavior when publishing to players. For larger deployments, we recommend using the Simple File Network or BrightSign Network publishing methods instead. 

Note: Local File Networking is not supported on Windows XP.

By default, BrightAuthor uses Bonjour to automatically discover BrightSign players on the local network. If either Bonjour or BrightAuthor is blocked by your firewall software, then discovery won’t work. Bonjour is sometimes listed as "mdnsResponder" and uses UDP port 5353. It's also possible this is just a temporary issue; the list often takes a few seconds to refresh after after you select the Publish > Local File Network or Manage > Local Network tabs.



  1. If BrightAuthor has Bonjour enabled (by default it is), ensure the Bonjour service is running in Services.
  2. Update Bonjour.  If it's already installed, uninstall it and reboot, then reinstall it.
    The Apple AirPort Utility includes Bonjour.  You can uninstall Apple Software Update and the AirPort applications after it completes installing, just leave Bonjour.
  3. Verify that you are using the latest production version of BrightAuthor software and player firmware (That your player suppports) available on the Downloads page.
  4. Verify that the SD card is inserted into the player and has not been manually edited since Device Setup. There is a program installed on the card during device setup that listens to publish requests from BrightAuthor.
    • If you run setup, then remove the sd card and publish a local presentation to it, you won't be able to add the player to BrightAuthor.
  5. Perform the Device Setup process again.
  6. Verify that you don’t have an active VPN connection. Local File Networking is only supported on the same subnet.
  7. Make sure that your firewall software is not blocking connectivity between BrightAuthor and the player.
  8. Disable proxy settings in Internet Explorer.
  9. Hit the refresh button on the Publish > Local File Network or Manage > Local Network tab.
  10. Leave the Publish or Manage tab, then return.
  11. Add the player manually using the player IP address.

Notes: Some users have reported that antivirus software that includes network components can block Bonjour (e.g., Kaspersky antivirus). Try temporarily disabling antivirus software or adding brightauthor as a trusted application.


Adding Unit Manually

If automatic discovery isn't working, try adding the unit manually. In BrightAuthor, navigate to Publish > Local File Network, click the Add icon under Publish, and enter the IP address of the player.

    To be more specific, is there a list of things that may still be quickly ordered (including in Europe)?

    We like using BrightSign's optical audio output.

    When a firewall prevents access to either Bonjour or BrightAuthor, discovery fails. UDP port 5353 is used by Bonjour, which is also known as mdnsResponder. Nevertheless, the delay in the list refreshing after selecting the Publish > Local File Network or Manage > Local Network tabs might only be momentary. dordle

    Discovery is unsuccessful when a firewall blocks access to Bonjour or BrightAuthor. Bonjour, which is also known as mdnsResponder, uses UDP port 5353. However, there might just be a brief pause in the list updating after selecting the Publish > Local File Network or Manage > Local Network tabs.

     If a firewall prevents Bonjour or BrightAuthor from communicating, discovery will fail. Bonjour, also known as mdnsResponder, is a service that listens on UDP port 5353. If you pick Publish > Local File Network or Manage > Local Network, the list may not immediately refresh. basketball stars
