Hey David, What language are you working with and where is your server running?
It's likely your connection is being downgraded by middleware (like Cloudflare, AWS application load balancers, nginx, etc). gRPC requires HTTP/2 all the way through to the server, and in some cases some additional configuration. For example, the nginix Kubernetes ingress controller requires additional annotations to terminate TLS and swap over to cleartext (if terminating at the edge).
