|The AP did not receive a valid IP address via the DHCP.
||Ensure that the DHCP server is on and available on the VLAN/subnet to which the AP is connected. If the AP still fails to get a valid IP address, you can reboot it to see if the problem is resolved.
|Unable to connect to the server.
- Ensure that the server is running and is reachable from the network to which the AP is connected. If a firewall or a router has Access Control Lists (ACLs) enabled between the AP and the server, ensure that traffic on UDP port 3851 is allowed.
- Use the IP-based server discovery method and ensure that you have correctly entered the DNS name, wifi-security-server, on the DNS server.
- Ensure that the DNS server IP addresses are either correctly configured, or are provided by the DHCP server.
- The AP might fail to authenticate with the server. In this case, an 'Authentication failed ' event is raised on the server. Refer to the event for recommended action.
|The AP has encountered a problem.
- If you are using Arista Cloud Services, then open the TCP port 443 (SSL). If you have an on-premises installation, then open UDP port 3851 and port 80.
- If you are using a Proxy, Web Accelerator, or URL Content Filter between the AP and the Internet, ensure that the settings allow communication between the AP and Arista Cloud Services.
