  • Is the MAC address correct on the account?
     
  • Is the device type correct on the account?
     
  • Is the device assigned to a user on the account?
     
  • Is the Server Address entered correctly?
     
    • No typos
       
    • No spaces at the beginning or end
       
  • Adjust the DNS Server
