can't connect to radius server

If the radius server in debugging mode isn't showing any sort of 
access-request coming from the client, then the requests simply aren't 
reach the server.  This could be due to firewalling, your client looking 
at the wrong host/port, or a variety of other things.  I'd suggest using 
tcpdump to see if the packets sent from the client are even reaching the 
radius server.

tcpdump port 1812

If you see nothing when the client should be sending access-requests 
then you have a networking issue to solve.
