Failed to send a RADIUS/1.1 resource-unavailable response for a reverse request
RADIUS/1.1 resource-unavailable response could not be sent.
Logged when local reverse-request processing fails and Radiator cannot return the RADIUS/1.1 resource-unavailable response. The error field describes the send failure.
Check error and preceding reverse-request failures. A closed backend connection or network
failure can prevent the error response from being delivered.
