Airport Extreme does not see My Cloud HOme

When I use terminal I see mac address for My Cloud Home , but when I access router, (airport extreme) it does not show up, backups start , then get error network stopped backup, I disabled security , but still have problem.

You should follow the steps mentioned in below article to get My Cloud Home on macOS.

My Cloud Home shows up in ARP table, but when I try to backup I get an error message that my network interrupted the backup, I cannot find the problem. Any suggestions Please.
