  1. Is the MAC address correct on your account?
     
  2. Is the device type correct on your account?
     
  3. Is Tag SN to UA enabled?
     
  4. Is the Server Type set correctly?
     
  5. Is the Server Address entered correctly?
     
    • No typos.
       
    • No spaces at the beginning or end.
       
  6. Adjust the DNS Server
