Hi Everyone,

Currently im evaluating temporal io for my future project, im having trouble with deployment in kubernetes,

 ![image](https://us1.discourse-cdn.com/flex016/uploads/temporal/original/2X/b/bbbfcc2353515ba4c9fbfb18d6b12ee7cf8c9c45.png)

and based some forum post we can health check directly using grpcurl, but it is not working with tctl, also my worker cant connect to frontend server,

are there any pointer on this problem?

thank you!

managed to connect to my frontend server using this connection option:

```nohighlight
	c, err := client.Dial(client.Options{
		HostPort: "frontend-temporal.pawonmburi.com:443",
		ConnectionOptions: client.ConnectionOptions{
			TLS: &tls.Config{},
		},
	})

```

thanks!
