Product: [Anthos Service Mesh](https://cloud.google.com/anthos
Rule class: WARN - Something that is very likely to be wrong

Description

The error code 111 typically corresponds to the ECONNREFUSED error in Linux which means that the connection was refused by the server(sidecar). This generally indicates that no process is listening on the IP:Port combination that the client is trying to connect to

Remediation

Verify that the application port in the pod is correctly configured and responding to the defined server port. Use tools like curl or netcat to test connectivity to the application port from within the pod. Ensure there are no misconfigurations or firewall rules blocking the connection.
