Do connections automatically reconnect?

[Mirko-von-Leipzig]

If a client connection breaks due to network issues or the server temporarily going offline, does the connection re-establish itself when the server comes back online?

There are a bunch of issues and discussions surrounding it (and similarly retry). Some suggest that with lazy_connect it does automatically reconnect - but maybe only once? Or only after some timeout?

If it doesn't automatically reconnect, how do I repair a broken connection in a proxy situation? That is, my server has a gRPC client as part of its state which I clone for each request. Do I need to recreate this client - implying that I now need mutable shared state to update the state's client if I determine its broken?
