In addition to my tcpdump analysis where it does not classify it as http2
I tries haproxy also does not classify it as http2 packet,
haproxy rejects with following line,
use_backend test_backend if { ssl_fc_npn -i h2 }
but works with following line,
default_backend test_backend

Thanks.

Looking at other replies and going thru other documents, i hope grpc cannot

But my issue is at least half of the time, after Ser

The main gRPC libraries *only* use HTTP/2. As you saw, they negotiate the
same protocol during NPN step of TLS handshake: "h2". It is more likely
that whatever analysis tool you used in the first case did not recognize
"h2" as the HTTP/2 protocol, so treated it as an unknown application
protocol.
Thanks for the prompt response.
We use Python grpcio 1.0.0.
No as i mentioned, for now version will not be updated as Network device i
am talking about is already deployed in customer networks.
We have to make our application work with this for now.
My question is more towards,
What does grpc r
What language(s) are you using gRPC with? In any case, it will be very hard
for us to help with such an old version; is there any way for you to update
