[RADIATOR] AuthRADIUS : Could not find a working host to forward messages

Hi,

duplicates mean that a request wasnt answered quickly enough - usually caused by a slowness
in the backend authentication systems....the NAS has resent a request as it didnt get a reply
(so if requests are being silently dropped that can happen too....)
