"unable to connect" is the result. Many things can cause it, from
incorrent radius IP/secret settings on AP to firewalls blocking

you can't test UDP with telnet. Try the included radtest and radclient

does it print incoming packets and process it?
does tcpdump (or whatever packet capture tools you have) shows incoming packets?
