I don't where you're looking at to see the error. But you can check RADIUS connectivity at GUI, User & Device->RADIUS Servers->edit "server_name" and "Test Connectivity" button. When you hit it and enter one of username/passwd of users, you should see RADIUS request then reply (UDP 1812 on server side) in "diag sniffer packet any 'host SERVER_IP' 4" like below:
19.058198 lan out 192.168.1.254.3949 -> 172.16.1.1.1812: udp 52 20.060076 lan in 172.16.1.11.1812 -> 192.168.1.254.3949: udp 20
If you don't see them, something is wrong with the RADIUS config on the FGT. Not much to configure though; server IP, seret pass, and nas-ip generally.
I would check logs on radius server and client. If the secret is wrong, or wrong defined service-port, or if the system set for DTLS-TLS these will generate almost no response back to the radius-client. You can dump on packet captures to see the radius-accept/reject messages.

Are you doing this over VPN?
yes over vpn
I can access to freeradius using another fortigate but on this fortigate I can not access , radius service working on 1812 port
If your running it over VPN than you'll need to specify a source IP for radius.
If you're using VDOM these would be the commands
c v
edit "vdom name" No Quotes
config user radius
edit "Name you gave it" no quotes
set source-ip "Firewall LAN ip" no quotes
end
end
if you do not have VDOM's enabled the commands are
config user radius
edit "Name you gave it" no quotes
set source-ip "Firewall LAN ip" no quotes
end
end
Try those and let me know if that helped or if you have any questions
If a server is available behind VLANs, make sure to add source-Ip as that actual interface or LAn IP, not VLAN IP.
