Using caddy with grpc

Help
1

Hi, i have a problem mapping my domain to a running grpc app. This is how my current configurations looks

grpc.brimble.io {
    tls {
        protocols tls1.2 tls1.3
    }
    reverse_proxy h2c://localhost:50051 {
        transport http {
            versions h2c 2
        }
    }
}

When i make a request to it, i get a Operation cancelled feedback
