Domain DNS zone is hosted externally and not managed by Plesk Panel.
An attempt to download a snapshot from Web Presence Builder GUI fails with the below error:
Internal Parallels Presence Builder error. File: /opt/psa/admin/externals/Zend/Http/Client/Adapter/Socket.php; Line: 235 Message: Unable to Connect to tcp://www.domain.com:80. Error #0: php_network_getaddresses: getaddrinfo failed: Name or service not known; Code: 0
Also import of the snapshot to a domain fails:
The issue occurs in case if DNS is handled externally, not by Plesk service, and a registrar suspends the domain for which we are trying to perform download\import.
Add the corresponding domain to the hosts file on a server:
echo <domain_ip_address> domain.com www.domain.com >> /etc/hosts
Where the is the IP address which is assigned to the domain which causes the issue in Plesk Panel.
