RSA key + TOTP authentication problem

Question
3

I’ve tested normal authentication only via RSA key and it’s work fine.
Accually I must attach some application because in other way privacyIDEA
don’t allow me to attach machine to TOTP token.
I’ve check radius log and on privacyIDEA server it receive some thing like
this:

Error: Failed binding to authentication address * port 1812: Address
already in use
Error: /etc/freeradius/radiusd.conf[240]: Error binding to port for 0.0.0.0
port 1812
Error: Ignoring request to authentication address * port 1812 from unknown
client 192.168.43.96 port 49567

I’ll also attach my radius server configuration.
