根因分析

TCP 连接被远程对端重置，原因可能是崩溃、超时或防火墙干扰。

English

The TCP connection was reset by the remote peer due to a crash, timeout, or firewall interference.

解决方案

  1. Configure the server to handle graceful shutdown and increase idle timeout. Example in Go: server := grpc.NewServer(grpc.KeepaliveParams(keepalive.ServerParameters{MaxConnectionIdle: 5 * time.Minute}))
  2. Use a connection pool with retry logic. In Python, use grpc.aio with automatic reconnection: channel = grpc.aio.insecure_channel('localhost:50051'); await channel.channel_ready()
  3. Check firewall or load balancer settings for idle connection timeouts. Increase TCP keepalive settings on both client and server (e.g., net.ipv4.tcp_keepalive_time=600).

无效尝试

常见但无效的做法:

  1. 80% 失败

    Connection reset is not a timeout issue; longer timeouts won't prevent the peer from resetting the connection.

  2. 70% 失败

    TLS is not the cause; disabling it reduces security without fixing the reset.

  3. 85% 失败

    The server or network issue persists; client restart doesn't address the root cause.
