Issue Slave dns do not work on some servers

Hi!

For some reason Slave sync stops working on some servers, on some shows "red circle" time to time.
So for example I see next on extension's page ( Plesk Obsidian 18.0.64 #1 Web Host Edition):

and this on slave in the logs:

Feb 24 15:34:51 ns1 named[3022563]: rejected command channel message from 9*.***.***.197#48375

After one or few F5 (reload) I see again "green circle".

Another server got "red circles" always, if I'm trying to run:

/usr/sbin/rndc -b 1***.***.***.225 -s 1**.***.***.208 -p 953 -y rndc-key -c /usr/local/psa/var/modules/slave-dns-manager/slave_1**.***.***.208.conf status
rndc: connection to remote host closed
This may indicate that
* the remote server is using an older version of the command protocol,
* this host is not authorized to connect,
* the clocks are not synchronized,
* the key signing algorithm is incorrect, or
* the key is invalid.

and on the Slave's side:

invalid command from 1**.***.***.225#42397: bad auth

or

invalid command from 1**.***.***.225#50807: expired

Hope you will help me.

This https://support.plesk.com/hc/en-us/...invalid-command-from-127-0-0-1-41838-bad-auth did not help because key are identical

For now it seems like time sync issue.
my NTP extension did not work as expected, so I reinstalled it and synchronized time, after that I can't see errors but I will monitor it
