  • Be sure you have an active server and reachable by the connected. If a firewall or a router has Access Control Lists (ACLs) enabled between the AP and the server, allow traffic on UDP port 3851.
  • Use the IP-based server discovery method and be sure you correctly entered the DNS name, wifi-security-server, on the DNS server.

  • The AP might fail to authenticate with the server. In this case, an 'Authentication failed ' event logs to the server. Refer to the event for recommended action.
