That depends on how you got the certificate in the first place. How did you?
Also, looking at the certificates issued for your domain I see some room for improvement: you could add the hostnames stellamarisdubai.ae and www.stellamarisdubai.ae into a single certificate. Perhaps you could include crm.stellamarisdubai.ae too, so you'd only have a single certificate for all three hostnames. How? That depends on which ACME client you've used to get the certificates in the first place.
