Root Cause

The underlying HTTP/2 transport was closed while an RPC was in flight. Causes include server shutdown, keepalive timeout, or a proxy (e.g., Envoy) closing idle connections.

generic

中文

RPC 进行中时底层 HTTP/2 传输被关闭。原因包括服务端关闭、keepalive 超时，或代理（如 Envoy）关闭空闲连接。

Workarounds

  1. 85% success 
    conn, _ := grpc.Dial(addr,
    grpc.WithKeepaliveParams(keepalive.ClientParameters{
        Time:                30 * time.Second,
        Timeout:             10 * time.Second,
        PermitWithoutStream: true,
    }),
)
  2. 80% success 
    for {
    resp, err := client.Get(ctx, req)
    if err == nil { return resp, nil }
    c := status.Code(err)
    if c != codes.Internal && c != codes.Unavailable { return nil, err }
    time.Sleep(backoff.NextBackOff())
}

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The response body is empty; downstream code will fail parsing nil/empty data.

  2. 80% fail

    WithBlock only affects initial dial; it does not prevent mid-call transport closure.
