grpc server exited with error: %s

Error message

grpc server exited with error: %s

What it means

Logged when the peer's main gRPC server goroutine exits: peerServer.Start() returned a non-nil error (e.g., listener failure or accept-loop error), which is wrapped and pushed to the serve channel to shut the peer down.

Solutions

1. Check whether the listen address/port is already in use or lacks permissions
2. Inspect the logged underlying error for TLS or socket issues
3. Restart the peer after freeing the port/fixing TLS config
