  You're trying to debug the server, but you're looking at the output of the client.  Why?

  This is extensively documented.  When you join the list, you get a message containing that link, and asking you to read it.

  We don't need to see the output of radclient.  We don't need to see the configuration files.

  The only solution is to read the debug output.

  What is likely going wrong is that the entry in "authorized_macs" doesn't match what the server is receiving in the User-Name attribute.  If you read the debug output, you will see this clearly.
