This is an `HTTP Status Code `_ that can mean any of several things. Often it indicates a network communication issue between a web browser and a web server. During AREDN |trade| firmware installs you can usually resolve a *Bad Gateway* issue by doing one or more of the following things: + +* Refresh or Reload the URL for your node. +* Clear your browser cache and delete cookies. +* Close your browser and restart a new session. +* Use a different web browser program or a *Safe Mode / Incognito* browser window. +* Unplug and reconnect the Ethernet cable from your computer to ensure that your machine has received a new DHCP IP address on the same subnet as the node's updated IP. + +Post-Install Steps +------------------ Once your device is running AREDN |trade| firmware, you can display its web interface by connecting your computer to the LAN port on the :abbr:`PoE (Power over Ethernet)` and navigating to the following URL: ``http://localnode.local.mesh`` Some computers may have DNS search paths configured that require you to use the `fully qualified domain name (FQDN) `_ to resolve *localnode* to the mesh node's IP address. Each node will serve its web interface on both port 80 and 8080.
