Both appear to expose the same gRPC service, but the one on port 9201 uses [gRPC-Web](https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-WEB.md), which can use HTTP/1.1, whereas the one on port 9200 uses HTTP/2, which is what most gRPC tools expect. The Starlink router also exposes a gRPC service, on ports 9000 (HTTP/2.0) and 9001 (HTTP/1.1).
