From the logs, it's clear that the first connection attempt failed due to a "RADIUS authentication failure" — this usually indicates the client entered incorrect credentials.

Interestingly, a minute later, the logs show a "RADIUS authentication success", immediately followed by the full WPA 4-way handshake and "client-authentication", which confirms that the issue was resolved after correcting the credentials.

The Fortinet study guide also states that authentication failures like this are commonly caused by user misconfiguration or invalid credentials, especially in WPA3 Enterprise environments.
