I would like to use gRPC in .net for communication between my microservices. My microservices will always be on a local network, deployed on a local docker server. Exposed to the ui (blazor wasm) via a reverse proxy. So the problem I have so far is this: All grpc required Http2 and Http2 requires https, and https requires certificates that I don't have, I...
