• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue Repair Plesk Obsidian after Lightsail Instance reboot and Static IP assignment

J Robinson

New Pleskian
Hi,
I'm trying to help a client who setup Plesk on Lightsail for a single website and, initially, did not have a Static IP assigned.
A wordpress site was built and went into production but hit problems with sending email.

Whilst trying to resolve this the customer has since assigned a static IP to the Lightsail instance and at some point rebooted.

This means that the instance has had at least three Public IP's PublicA (initial), PublicB (after reboot) and now PublicC (StaticIP)

They have updated the NS records for the domain to point to PublicC (StaticIP) and allowed propagation to complete and rebooted the Plesk server on Lightsail which has picked up the change of Public IP Address and now displays the PublicC (Static IP) IP address alongside the Internal network address (172.x.x.x/24) allocated by Lightsail to the instance.

The problem appears to be that the DNS server on Plesk does not appear to be responding to any nslookup requests for the domain and typing the domain into a browser results in a 'server IP address could not be found' message.

Please could someone direct me to a KB article to help resolve this issue or talk me through how to get the DNS server working and therefore the site back online.

Many thanks in anticipation.
