Running multiple instances of servers on different hosts

Getting Help

I don’t understand something anyway, I run it in a goroutine, but nothing happens, something I’m doing wrong
scanServerConn := [3]config.GRPCConfig{conf.ScanConnect.ScanServerFir.GRPC, conf.ScanConnect.ScanServerSec.GRPC, conf.ScanConnect.ScanServerThi.GRPC}
for _, servConn := range scanServerConn {
go func() {
err := NewServerStart(servConn)
if err != nil {
log.Fatalf(“Can’t run server: %s”, err)
}
}()
}
