Hi, I have a grpc service and I am trying to expose it through Kong ingress but when I external services are trying to connect to it I see the call reaching the ingress and they get dropped here with the following error. 2020/06/08 12:51:21 [info] 22#0: *3645413 client sent invalid request while r…

Are you sending the requests over HTTPS, and do you have HTTP/2 enabled? gRPC normally uses HTTP/2 as transport, and by extension requires HTTPS to function. That log line suggests that you may have HTTPS, but do not have HTTP/2 enabled. It is normally enabled by default using the http2 parameter i…

Hi, Yes we are sending it over https an and we have http2 enabled using the environment variable as you can see in the pod manifest and from inside the pod itself. bash-5.0$ env | grep LISTEN KONG_ADMIN_LISTEN=0.0.0.0:8444 http2 ssl KONG_STATUS_LISTEN=0.0.0.0:8100 KONG_STREAM_LISTEN=off KONG_PR…

I see it in the nginx-kong.conf server { server_name kong; listen 0.0.0.0:8000; listen 0.0.0.0:8443 ssl http2; error_page 400 404 408 411 412 413 414 417 494 /kong_error_handler; error_page 500 502 503 504 /kong_error_handler; access_log /dev/stdout; error_log /dev/stderr inf…

That older post shouldn’t be relevant in current versions–the change linked from it is part of the service mesh code, which was removed in 2.0.0 . On earlier versions, that code changed parts of the TLS implementation; without it, we use the standard NGINX TLS and HTTP/2 implementation, and the direc…

Sorry for the late reply. The error seemed to be on the client sending the request (our case Thanos query) which wasn’t supporting a mix grpc and gpcs stores. We have to temporary moved to use grpc till the PR to use a mix of types of stores will be merged.
