Description

Reason 1

Solution

1. Host name / Server address
   
1. Copy either IP address or domain name (if your access point supports domain name for RADIUS server URL field) correctly from Zoho One.
   

1. We recommend using the Domain name instead of the Server IP Address. The Server IP Address may change over time, and if it does, you will need to manually update the new IP Address in the access point's admin console. Using the domain helps avoid manual updates and ensure uninterrupted connectivity.  
   
2. Paste it in your access point configuration without modification.
   
2. IP address type
   
1. It is recommended that the IP address used is Static.
   
2. If your organization switches to a new IP address,
   
3. Update the IP address in the RADIUS client info in Zoho One.
   
4. Or add all valid IP addresses in the client info section by clicking +, so that RADIUS server can authenticate all requests from the listed IP addresses.
   
3. Port number
   
1. Copy the Port number from the Server Information tab and paste it into the corresponding field in the access point.
   
4. Shared secret
   
1. Copy the shared secret from the Server Information page and paste it (without any extra spaces or characters) into the corresponding field on your access point.
   
5. Authentication type
   
1. Select EAP-TTLS(PAP) for credential-based authentication.
   

Reason 2

Solution

1. Ensure that the inbound and outbound UDP calls are allowed and not blocked.
   
2. Whitelist the RADIUS server URL and its IP addresses mentioned in the Server Information tab, so that the authentication requests from the user's device reaches Zoho One's RADIUS servers.
