Nature of Plesk DNSPROBE FINISHED ERROR

This error can happen as a result of the following:

1. We cannot access domains hosted on the Plesk server since it shows error in a browser like this: 

DNSPROBE FINISHED ERROR

2. The domain cannot resolve locally with explicitly specified NS:

# dig +short exampe.com @ns1.example.com
#

3. Dist-upgrade to Ubuntu 20 may be performed recently.

Generally, this error can occur as a result a BIND misconfiguration.

You can see a sample of the error message:

# systemctl status bind9
* named.service – BIND Domain Name Server
Loaded: loaded (/lib/systemd/system/named.service; enabled; vendor preset: enabled)
Drop-In: /lib/systemd/system/bind9.service.d
`-respawn.conf
Active: active (running) since Sat 2020-10-03 02:18:00 GMT; 20min ago
. . .
`-236526 /usr/sbin/named -f -u bind


How to fix Plesk DNSPROBE FINISHED ERROR ?

1. Initially, we connect to the server via SSH.

2. Then we edit /etc/default/named config file. Here, we replace the OPTIONS parameter.

Before:

# cat /etc/default/named
. . .
OPTIONS="-u bind"

After:

# cat /etc/default/named
. . .
OPTIONS=" -t /var/named/run-root -c /etc/named.conf -u bind -n 2"

3. Eventually, we restart the BIND service:

# systemctl restart bind9​

4. Finally, we repair DNS for domains:

# plesk repair dns

This should fix the error.
