  You have a firewall between the RADIUS server and database.  The
firewall is dropping the RADIUS -> database TCP connections.

  I have *no* idea why anyone thinks this is a good idea.  The firewall
(if any) should be configured to allow ANY TCP (RADIUS -> DB : port).
But many people create rules allowing only "established" TCP
connections, and then the firewall helpfully loses track of which
sessions are established.

  Stop breaking your network.
