Actually, I was mistaken.
Both server and client are using the same protos.
I have checked again and again, and even checked using Beyond Compare - and
yes the protos are definitely the same. I have regenerated both c++ and
python. But I cannot solve this problem.
I turned on tracing on the server, and I see the following, which doesnt
really give any insight.

On the client, which is vaguely more insightful, but not much more, is:
