Using the oPi as the server, I'm getting authentication errors: "Error sending request: No valid RADIUS responses received"

Debug output for the non-working server: ... Failed binding to authentication address * port 1812: Address already in use /etc/freeradius/radiusd.conf[273]: Error binding to port for 0.0.0.0 port 1812
