Unable to publish website in Plesk Web Presence Builder: Unable to Connect to ssl://feedback.pp.parallels.com:443: Name or service not known

Plesk for Linux kb: technical

Applicable to:

  • Plesk for Linux

Symptoms

  • When clicking the Publish button in Plesk Web Presence builder, the following error is displayed:

    PLESK_ERROR: 500 Zend_Http_Client_Adapter_Exception
    Unable to Connect to ssl://feedback.pp.parallels.com:443. Error #0: php_network_getaddresses: getaddrinfo failed: Name or service not known

  • A similar error can be found in the /var/log/plesk/sitebuilder.log file:

    PLESK_ERROR: [EMERG] /sitebuilder/JsonApi/ Zend_Http_Client_Adapter_Exception: Unable to Connect to ssl://feedback.pp.parallels.com:443. Error #0: php_network_getaddresses: getaddrinfo failed: Name or service not known
    file: /usr/local/psa/admin/plib/vendor/plesk/zf1/library/Zend/Http/Client/Adapter/Socket.php
    line: 235
    code: 0

  • Web Presence Builder debug mode is enabled:

    # grep -i debug /usr/local/sb/config
    [debug]
    debug=on

Cause

feedback.pp.parallels.com is a deprecated service for error reporting that was used for different Plesk components. This service is now working on a different URL, but the old URL is still present in the Web Presence Builder code.

Resolution

  1. Connect to the server via SSH.

  2. Open the /usr/local/sb/config file for editing, for example, in the vi editor:

    # vi /usr/local/sb/config

  3. Add the following block to the /usr/local/sb/config file to disable error reporting:

For Plesk Obsidian 18.0.50 and above:

CONFIG_TEXT: [internal]
send_errors = 0

For Plesk Obsidian 18.0.49 and below:

CONFIG_TEXT: [internal]
send_errors = false

  1. Save changes and close the file.

Since there was an error report, it means that there was an actual error that prevented the publishing in the first place. If the publishing fails with disabled error reporting, further investigation may be required.
