Unable to access a BrightSign at that IP address error message

If you receive the error "Unable to access a BrightSign at that IP address" when attempting to publish to a Local File Networking player in BrightAuthor, see below.

• Problem:
  The player has not been, or is no longer, configured for Local File Networking usage
  Resolution:
  Apply new Local File Networking setup files to the player.
  For Series 3 (models ending in 3) and newer players, you can clear the content of the player's storage device, Factory Reset the player, then go back through On-Device Setup.
  Otherwise you can write new setup files to the player's storage from BrightAuthor (Tool>Setup BrightSign Unit) or deliver setup files to the player via the DWS.
• Problem:
  You're using DHCP addressing without an address reservation for the player and the router or DHCP server rebooted or changed which address the player has.
  Resolution:
  Power up the player without storage to determine what IP address it currently has from the information screen it displays.  Replace the storage and reboot the player after you have noted the current IP address.
  Refresh the Networked Units list to see if you get a new/updated player entry
  Add the player's new IP address to the Networked Units list
  Definitely consider adding an address reservation to the DHCP server so the player's address is predictable
• Problem:
  The published presentation or content has put the player into a reboot loop.
  Resolution:
  Apply new player setup files to clear the presentation schedule and stop the presentation from crashing the player.
  
  Of course the easiest way to bring a player out of a reboot loop is to apply player setup files to the player's storage again.  This will clear the player's presentation schedule so the presentation won't run and crash the player again.  But if you cannot physically access the player, you can still recover as long as the Diagnostic Web Server is accessible.
  
  Keep trying to Disable Autorun from the Diagnostics tab of the player's local Diagnostic Web Server (http://playerIPaddres/index.html - replace playerIPaddress with the player's LAN IP address) or remote Diagnostic Web Server (from http://BSN.cloud or BrightAuthor:connected) until you get a response from the player.
  
  After you see the response, the player will reboot with the autorun disabled, then you can use the method described in Publishing Setup Files via Diagnostic Web Server to create, package, and deliver a new set of player setup files to the player.
  
  After setup is applied you should be able to publish to the player again.
  
  Check your presentation for invalid data feeds, out-of-spec media, and resource-hungry HTML sites before publishing again.
  
  Try updating the player firmware/OS.

• Problem:
  The player's storage device has been removed or is not readable.
  Resolution:
  Put the player's storage device in a PC and see if it can be recovered.
  Replace the storage device and write new Local File Networking configuration files to it via BrightAuthor's Tools>Setup BrightSign Unit

• Problem:
  The player has been disconnected from the network or power
  Resolution:
  Plug it back in.

• Problem:
  Network access to the player on ports 80, 8008, and/or 8080 is blocked
  Resolution:
  Consult with IT to ensure the BrightAuthor machine can communicate with the player.
  See if you can open http://playerIPaddress:8080/GetID (replace playerIPaddress with the player's LAN IP address) from a web browser on the same network as the player.
• Problem:
  BrightAuthor access to ports 80, 8008, and/or 8080 is blocked
  Resolution:
  Consult with IT to ensure the BrightAuthor machine can communicate with the player.
  Check any third-party antivirus/firewall/security software.
