rpc error: "error reading server preface: EOF"

I've see this once (not reproducible) while starting a `default` instance using latest `master` branch:

```
INFO[0022] [hostagent] Forwarding "/run/lima-guestagent.sock" (guest) to "/Users/jan/.lima/default/ga.sock" (host)
WARN[0022] [hostagent] guest agent events closed unexpectedly error="rpc error: code = Unavailable desc = connection error: desc = \"error reading server preface: EOF\""
INFO[0022] [hostagent] The optional requirement 1 of 2 is satisfied
```
