Radius backend min-connections connect failed
RADIUS backend minimum connection attempt failed.
Emission
Log level: DEBUG
Per-request tracing: No
Promotion: WARN
Logged when a background connection attempt fails while maintaining the configured minimum RADIUS
backend connections. The error field describes the connection failure. Without an
alerts block, DNS, TCP connection, and TLS
handshake timeouts are reported only by their own messages. When an alerts block enables backend
incidents, failures across this backend update one connectivity incident until all required
connections recover.
Repeated failures usually mean the backend is unavailable or DNS, routing, TLS, or local socket setup is failing.
Check the error and the backend connection min
setting. Lower min only when maintaining warm connections is not required.
