rndc: connect failed: 127.0.0.1#953: connection refused

I fixed it myself , it was a permission and ownership issue.To fix it you need to execute those ssh commands

Fix rndc connection refused error

chown root:named /etc/rndc.key

chmod 640 /etc/rndc.key

clear the file of directory /var/cache/bind/ and after in terminal bash /etc/bind/bind9 restart
