kb: technical Plesk Onyx for Linux ABT: Group B

Applicable to:

  • Plesk Onyx for Linux

Symptoms

When creating a new domain alias, the operation fails with the following error message in Plesk (in this example, domain alias example.net for example.com):

PLESK_ERROR: Error: Unable to add the ipv4.example.net. IN A 203.0.113.2 record to zone example.net: DNS record already exists.

Cause

The domain, for which a domain alias is created, contains duplicate DNS records.

In this example, there is a duplicate DNS entry for example.com that points to the same IP address 203.0.113.2 at Domains > example.com > DNS Settings.

Resolution

  1. In Plesk, go to Domains > example.com > DNS Settings.

  2. Select the duplicate DNS entries and remove them.

    This error can occur if DNS for the (sub)domain is disabled.  Enable DNS, delete the A and/or AAAA records, and disable DNS again.
