Without additional details like the domain name it's tough to determine the cause of the specific error. I suggest giving our hosting team a call to look into your issue. They can be reached by dialing 480-463-8824.
this is the first time i have bought domain and hosting together so I am from Somalia, how can i dial the given number
can i dial by skype or whatsapp?
anyway, here is more information about my new hosting and domain
