I'm trying to use a haproxy instance to correctly redirect the requests from the client to the server. But the client can't connect using the haproxy, it only works when I do the request directly to the server.
The unique message error is printed from the client, saying:
Request not completed. Error: Error: 14 UNAVAILABLE: No connection established
I'm creating the certificates using openssl.
I think, there's a problem in the haproxy config file, since works normally when "Client -> Server".
My haproxy config file:
global
daemon
defaults
mode http
timeout connect 5s
timeout client 60s
timeout server 60s
frontend grpc-front
bind *:8000 proto h2 ssl crt /usr/local/etc/haproxy/ca.pem
default_backend grpc-back
backend grpc-back
server test-server test-server:8000 check fall 3 proto h2 ssl verify required ca-file /usr/local/etc/haproxy/ca.pem
Observations:
- The project works normally when connecting directly to the server (Client -> Server);
- The CN defined in the server's certificate is:
test-haproxy; - It also works normally when not using TLS;
- All applications (client, haproxy, server) are dockerized and properly connected to each other.
