Troubleshoot Troubleshooting Device Connectivity States

Last updated: Aug 27, 2025

Device Connectivity States

You can view the connectivity states of the devices onboarded in your Firewall Manager tenant. This topic helps you understand the various connectivity states. On the Security Devices page, the Connectivity column displays the device connectivity states.

When the device connectivity state is 'Online' it means that the device is powered on and connected to Firewall Manager. The other states described in the table below usually occur when the device is running into problems for various reasons. The table provides the method to recover from such problems. It may be that there is more than one problem causing the connection failure. When you attempt to reconnect, Firewall Manager will prompt you to fix all of these problems first before performing the reconnect.
