Let's start with the server case because it's a bit easier. gRPC provides some built in healthchecking capabilities. Clients watch server health. When a server goes unhealthy, clients remove them from the pool.
gRPC doesn't necessarily surface connection primitives to your server side so it's probably not easy to get at the same information for clients. On the other hand, you could use something like a long lived bidi-streaming API to "simulate" a connection with a backend. You'll need to handle network disconnects, but you could use that approach to do some cleanup. While it's not C++, here's a go example where a server side streaming API cleans up a subscription <https://github.com/mjpitz/paxos/blob/main/internal/server/acceptor.go#L106-L110> when the client is disconnected.
