How to fix client-side error: "Endpoint read failed"?

[rkabh...@gmail.com]

I am seeing this error "Endpoint read failed" on the client-side with the below code following this example (https://github.com/grpc/grpc/blob/v1.4.5/examples/cpp/route_guide/route_guide_client.cc). Using grpc v1.4.5.

The error log is here: https://github.com/abhikeshav/test-code/files/1662114/grpcerror.txt

Any idea how I  can fix this?

    grpc::ClientContext context;

    grpc::Status status;

    gnmi::SubscribeResponse response;

    std::unique_ptr<grpc::ClientReaderWriter<gnmi::SubscribeRequest, gnmi::SubscribeResponse>> c = stub_->Subscribe(&context);

    std::shared_ptr<grpc::ClientReaderWriter<gnmi::SubscribeRequest, gnmi::SubscribeResponse>> cs (move(c));

    std::thread writer([cs, payload, operation]() {

       gnmi::SubscribeRequest r;

       gnmi::SubscriptionList* sl = new gnmi::SubscriptionList;

       populate_subscribe_request(r, payload, operation, *sl);

       cs->Write(r);

       cs->WritesDone();

    });

    while (cs->Read(&response))

    {

      debug_log("Getting subscription data");

    }

    writer.join();

    status = cs->Finish();

    if (!status.ok())

    {

      throw(error{status.error_message()});  // Seeing the error here

    }

This part of the error log seems most relevant. It states that the socket closed and the connection is no longer valid. I don't understand why this is the case as the grpc::ClientReaderWriter object is still active after the Read/Write requests are done?

Any idea what could be wrong with the code to cause this error?

I have the same issue using php, on my machine I use in docker without a problem, but on a remote server, I encounter the same problem with exact grpc and protobuf version.

Did anyone manage to solve this problem?
