As you can see from the logs: - `connect() failed (111: Connection refused)` error, indicating that APISIX was unable to connect to the backend service. - `upstream prematurely closed connection` error, indicating that the backend service closed the connection abnormally while processing the request. My personal deduction from this information: 1. The backend gRPC service may be intermittently unavailable, are there any checks? 2. Recommended to turn on [health check](https://apisix.apache.org/docs/apisix/tutorials/health-check/) for upstream to detect and remove unhealthy nodes in a timely manner. -- This is an automated message from the Apache Git Service.
