Some admin may concern the issue where a user is not on the Nebula Cloud Auth Server list was able to connect to SSID.

When SSID currently security or sign-in method configured as auth with Nebula Cloud Auth Server. It means when a device tries to connect to the network, it needs to authenticate via the server.

However, if at that moment, if there is a network issue preventing the server from being reached, the system will react based on the preset instructions.

The SSID settings are configured to "Allowed: Client devices can access the network without signing in, except they are explicitly blocked." This means that if the server cannot be reached, devices are still allowed to connect.

If you prefer that no devices connect without successful authentication, you should consider changing the setting to "Limited: Only currently authorized clients will be able to access the network." This setting will ensure that only devices that have successfully authenticated will be allowed access, even if there is a temporary server issue.
